CVE-2023-22089Network attack vector

Unauthenticated server takeover

Published Oct 17, 2023 · Updated Mar 6, 2025

An unspecified flaw in Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 allows remote attackers to take over the server via T3 or IIOP. Oracle identifies the affected locus only as the Core component and has not published the incorrect operation performed on protocol input. Unauthenticated network reachability to a T3 or IIOP listener is sufficient, and successful exploitation compromises confidentiality, integrity, and availability.
