Summary

The openjdk-orb component in Red Hat JBoss Enterprise Application Platform (EAP) running with -secmgr honours attacker-supplied CDR codebase URLs during object unmarshalling on port 3528, an incomplete fix for an earlier flaw (CWE-829). An unauthenticated remote attacker can load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run.
