CVE-2012-4418: Apache Axis2 Vulnerable to XML Signature wrapping attack

The provided vulnerability reports (CVE-2012-4418, GHSA-88r4-38gc-97p4) describe an XML Signature wrapping attack in Apache Axis2, but they do not explicitly name specific vulnerable functions or file paths. The JIRA tickets (AXIS2-5930, AXIS2C-1694) reference dependency updates and general security fixes but lack code-level details. The core issue likely resides in how Axis2 processes XML signatures (e.g., improper validation of signed elements or insecure reference resolution in SOAP message handling). However, without access to the original patch code, commit diffs, or explicit documentation linking the vulnerability to concrete functions, it is not possible to identify the exact vulnerable functions with high confidence. The vulnerability stems from architectural/design flaws in XML signature validation rather than isolated functions, as implied by the attack's nature.
