CVE-2024-21182Oracle WebLogic Server — unauthenticated data exposure over T3

Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 let an unauthenticated attacker who can reach the T3 or object-request-broker (IIOP) listeners read the data the server holds. Oracle's advisory does not say which flaw makes it possible.

YOUR NEXT MOVE

Apply Oracle's July 2024 Critical Patch Update now; block the T3 and object-request-broker listeners at the network edge — they should never face the internet.
