CVE-2023-22031Network attack vector

Authenticated hang or crash via undisclosed Core flaw

Published Jul 18, 2023 · Updated Sep 13, 2024

Denial of service in Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 allows remote authenticated users to cause a hang or crash via T3 or IIOP. Oracle identifies the affected locus only as the Core component and has not disclosed the operation that mishandles protocol input. Exploitation requires high privileges, network access to T3 or IIOP, and high attack complexity; successful attacks affect availability only.
