AI-Generated

The vulnerability affects the Apache CXF's JAX-RS XML Security module, where improper verification of cryptographic signatures allows an attacker to wrap unsigned content in a signed document, potentially leading to unauthorized access or manipulation of data. Organizations utilizing Apache CXF for XML processing should prioritize upgrading to versions 4.2.4, 4.1.9, or 3.6.13 to mitigate this risk.

Original NVD Description

Improper Verification of Cryptographic Signature vulnerability in Apache CXF's JAX-RS XML Security module. The JAX-RS XML Signature interceptors (XmlSigInHandler, XmlSigInInterceptor and the streaming XmlSecInInterceptor) did not ensure that the XML passed to the application was covered by the signature. An attacker with any document signed by a trusted key could wrap it in unsigned content, which the application would then treat as signed. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
