How to fix?

There is no fixed version for RHEL:9 cxf-rt-transports-jms.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cxf-rt-transports-jms package and not the cxf-rt-transports-jms package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Apache CXF's JMS transport deserializes the body of any inbound JMS ObjectMessage using native Java deserialization, with no type restrictions in place. Any attacker able to place a message on the service's JMS destination can submit a malicious serialized object, leading to denial of service or, if a suitable gadget class is on the classpath, remote code execution. The fix disables ObjectMessage deserialization by default, with a configuration switch to re-enable it if needed. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
