CVE-2025-29775

Ein entfernter anonymer oder lokaler Angreifer kann mehrere Schwachstellen in HCL BigFix ausnutzen, um Dateien zu manipulieren, erhöhte Privilegien zu erlangen, einen Denial-of-Service-Zustand auszulösen, vertrauliche Informationen offenzulegen und beliebigen Code auszuführen.

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in IBM App Connect Enterprise ausnutzen, um Sicherheitsvorkehrungen zu umgehen, Informationen auszuspähen oder seine Privilegien zu eskalieren

# Impact An attacker may be able to exploit this vulnerability to bypass authentication or authorization mechanisms in systems that rely on xml-crypto for verifying signed XML documents. The vulnerability allows an attacker to modify a valid signed XML message in a way that still passes signature verification checks. For example, it could be used to alter critical identity or access control attributes, enabling an attacker to escalate privileges or impersonate another user. # Patches All versions <= 6.0.0 are affected. Please upgrade to version 6.0.1. If you are still using v2.x or v3.x please upgrade to the associated patch version. # Indicators of Compromise When logging XML payloads, check for the following indicators. If the payload includes encrypted elements, ensure you analyze the decrypted version for a complete assessment. (If encryption is not used, analyze the original XML document directly). This applies to various XML-based authentication and authorization flows, such as SAML Response payloads. ### Presence of Comments in `DigestValue` A `DigestValue` should **not** contain comments. If you find comments within it, this may indicate tampering. **Example of a compromised `DigestValue`:** ```xml <DigestValue> <!--TBlYWE0ZWM4ODI1NjliYzE3NmViN2E1OTlkOGDhhNmI=--> c7RuVDYo83z2su5uk0Nla8DXcXvKYKgf7tZklJxL/LZ= </DigestValue> ``` ### Code to test Pass in the decrypted version of the document ```js decryptedDocument = ... // yours to implement const digestValues = xpath.select( "//*[local-name()='DigestValue'][count(node()) > 1]", decryptedDocument, ); if (digestValues.length > 0) { // Compromise detected, yours to implement } ```
