Vulnerability Note VU#858990

Original Release Date: 2004-04-09 | Last Revised: 2004-04-12


BEA WebLogic Server fails to properly associate a user's identity when a client attempts to connect multiple times using different client certificates.


BEA Systems describes WebLogic Server as "an industrial-strength application infrastructure for developing, integrating, securing, and managing distributed Java applications." WebLogic Server provides a feature that allows users to be issued client certificates. When connecting to the server, the client's certificate is associated with a specific user identity. There is a vulnerability in the way WebLogic Server associates client certificates with user identities. By supplying a different client certificate upon subsequent connections, the WebLogic Server may associate the client certificate with the incorrect user identity.

According to the BEA Security Advisory, the following versions of WebLogic Server and Express are affected by this vulnerability:

    • WebLogic Server and Express 7.0, released through Service Pack 4, all platforms


A user may gain access to another user's identity. According to the BEA Security Advisory, this vulnerability "allows one user to execute commands as another user."


Apply PatchBEA has released a patch to address this vulnerability. According to the BEA Security Advisory, it is recommended that users upgrade to Service Pack 4 and apply the patch.
