CVSS 7.5 HIGHEPSS 99.8%● KEVCWE-306
In short

Oracle WebLogic Server allows unauthenticated attackers to access sensitive data remotely through network protocols (T3, IIOP) without needing valid credentials. This is a critical vulnerability because it exposes confidential information to anyone with network access to the server.

Technical detail

An unauthenticated remote attacker can exploit missing or insufficient authentication checks in WebLogic Server's T3 and IIOP protocol handlers to gain unauthorized read access to critical data. The attack requires only network connectivity and has low complexity (CVSS 7.5), resulting in high confidentiality impact without authentication requirements (CWE-306: Missing Authentication).
