Summary

when EAP runs with -secmgr, the openjdk-orb's JDKBridge honours attacker-supplied CDR codebase URLs during object unmarshalling on :3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run.
