Lookup hijacking via unauthenticated NameService binds
Published Aug 11, 2026 · Updated Aug 11, 2026
Missing authentication in Red Hat JBoss EAP's IIOP NameService allows remote attackers to redirect JNDI lookups with bind requests. The listener accepts unauthenticated naming binds and associates attacker-chosen names with a malicious object request broker. Network reachability to the IIOP listener is sufficient, and later invocations can be intercepted or redirected without altering unrelated services.
