Mitigation checklist
- To mitigate this vulnerability, disable ObjectMessage deserialization in Apache CXF's JMS transport. This can typically be achieved through a configuration setting provided by the Apache CXF framework. Consult the Apache CXF documentation for specific instructions on how to disable ObjectMessage deserialization in your deployment. Disabling this feature may impact applications that rely on ObjectMessage for legitimate data transfer.
