Technical details
A vulnerability in the Console component of Oracle WebLogic Server (versions 14.1.2.0.0 and 15.1.1.0.0) is classified as an Open Redirect (CWE-601) that can lead to full server takeover. The flaw is easily exploitable by an unauthenticated attacker with network access via HTTPS. While the attack vector is network-based, successful exploitation requires user interaction (UI:R), typically involving a legitimate administrator clicking a malicious link or being redirected. If successful, the attacker can achieve high impacts on confidentiality, integrity, and availability, effectively compromising the entire WebLogic Server instance. Oracle has addressed this in the June 2026 security update.
