CVE-2022-21564Network attack vector

Unauthenticated partial service interruption

Published Jul 19, 2022 · Updated Sep 24, 2024

Denial of service in Oracle WebLogic Server 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0 allows remote attackers to interrupt service via T3 or IIOP. Oracle identifies the Web Services component but has not published the affected code path or the operation performed incorrectly. No authentication or user interaction is required; successful requests cause only a partial service interruption, not data access or modification.
