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 Oracle WebLogic Server Core component. This can be exploited by a remote attacker to execute arbitrary code using IIOP, T3 protocols. Successful attacks can result in the takeover of the Oracle WebLogic Server.

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 until a patch is available. Avoid using the T3 protocol for deserialization of untrusted data in the affected Oracle WebLogic Server versions until the issue is resolved.
