Root Cause Analysis
The vulnerability stems from the use of an outdated Apache CXF dependency (version <3.4.3) that allowed HTTP method spoofing via the '_method' parameter. The patches (commits 59cb673
and 8f8271e
) only update the CXF version in 'pom.xml' files, indicating the vulnerability resided in CXF's internal request handling logic, not in Opencast's own code. No specific functions within the 'opencast-common' package were modified or identified as directly implementing the vulnerable behavior. The issue was mitigated by updating the library dependency rather than modifying application code.
