I. ADVISORY

This vulnerability can occur when security roles and policies are being read from the deployment descriptors during deployment and an internal error occurs in one of the security providers during deployment. Some errors will not be reported and the application might deploy with incomplete security.

This vulnerability typically will cause an application to be left with incomplete security roles and policies. The exact form the problem takes is highly dependent on the security settings of the application and the type of error(s) that occurred in the security provider during deployment.

This advisory resolves the issue by ensuring that all errors are reported and causing the application does not deploy until those errors are resolved.

The following versions of WebLogic Server are affected by this vulnerability
  • WebLogic Server 8.1, released through Service Pack 2, on all platforms
  • WebLogic Server 7.0, released through Service Pack 5, on all platforms

II. SUGGESTED ACTION


Oracle strongly recommends the following course of actions.
  • For WebLogic Server 8.1: Upgrade to WebLogic 8.1 Service Pack 3.
