The WSEE runtime (WS-Security runtime) in BEA WebLogic Server 9.0 and 9.1 does not verify credentials when decrypting client messages, which allows remote attackers to bypass application security.

BEA WebLogic Server 8.1 through 8.1 SP5 does not properly enforce access control after a dynamic update and dynamic redeployment of an application that is implemented through exploded jars, which allows attackers to bypass intended access restrictions.

BEA WebLogic Server 6.1 through 6.1 SP7, 7.0 through 7.0 SP6, 8.1 through 8.1 SP5, and 9.0 allows remote attackers to cause a denial of service (server hang) via certain requests that cause muxer threads to block when processing error pages.

BEA WebLogic Server 8.1 through 8.1 SP5 stores cleartext data in a backup of config.xml after offline editing, which allows local users to obtain sensitive information by reading this backup file.

BEA WebLogic Server 6.1 through 6.1 SP7, 7.0 through 7.0 SP7, and 8.1 through 8.1 SP5 allows remote attackers to read arbitrary files inside the class-path property via .ear or exploded .ear files that use the manifest class-path property to point to utility jar files.

BEA WebLogic Server 8.1 through 8.1 SP5, 9.0, 9.1, and 9.2 Gold, when WS-Security is used, does not properly validate certificates, which allows remote attackers to conduct a man-in-the-middle (MITM) attack.
