Technical details

An unspecified vulnerability exists in the Core component of Oracle WebLogic Server versions 12.2.1.4.0 and 14.1.1.0.0. The flaw is easily exploitable by an unauthenticated attacker with network access via the T3 or IIOP protocols. Successful exploitation allows the attacker to bypass security controls to gain unauthorized access to critical data or complete access to all data accessible by the WebLogic Server. While the vendor classifies this as an 'unspecified' vulnerability (CWE-noinfo), it is frequently associated with improper handling of serialized objects or protocol-specific parsing issues in the T3/IIOP stacks. Users should apply the July 2024 Oracle Critical Patch Update (CPU) to mitigate this risk.
