Some vulnerabilities have been reported in BEA WebLogic Server, which can be exploited by malicious users to bypass certain security restrictions, and by malicious people to bypass certain security restrictions and compromise a vulnerable system.

1) A boundary error within the WebLogic plug-in for Apache can be exploited to cause a stack-based buffer overflow and compromise a vulnerable system.

2) An unspecified error allows users to access applications in admin state under certain unspecified conditions.

3) An unspecified error when upgrading Bea WebLogic Server 8.1SP3 to a higher version could result in previously protected applications being available to invalid users.

Successful exploitation requires that an auth-method as CLIENT-CERT is used.
