CVE-2024-21260Network attack vector

Unauthenticated denial of service via T3 or IIOP

Published Oct 15, 2024 · Updated Oct 16, 2024

Denial of service in Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 allows remote attackers to hang or crash servers via T3 or IIOP. Oracle identifies the affected locus only as the Core component and has not published the malformed operation or input that triggers the failure. Network access to an enabled T3 or IIOP listener is sufficient; the reported consequence is limited to a hang or frequently repeatable server crash.
