Technical details
The vulnerability is a remote code execution flaw in Oracle WebLogic Server's Core component that can be exploited by an unauthenticated attacker with network access via the T3 (Oracle proprietary) or IIOP (Inter-ORB) protocols. No user interaction or authentication is required; the vulnerability is easily exploitable due to low attack complexity. Successful exploitation results in complete compromise of the WebLogic Server, granting an attacker the ability to execute arbitrary code, read/modify data, and disrupt availability. Affected versions include 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. Patches or mitigations should be obtained from Oracle's security advisories.
