Name of the Vulnerable Software and Affected Versions Oracle WebLogic Server versions 10.3.6.0.0 through 14.1.1.0.0

Description The issue is related to insufficient input validation in the Core component of Oracle WebLogic Server, allowing an unauthenticated attacker with network access via IIOP, T3 protocols to compromise the server. Successful attacks can result in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data.

Recommendations For versions 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the IIOP and T3 protocols to minimize the risk of exploitation. Avoid using the vulnerable Core component until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
