IBM WebSphere Application Server post migration privilege escalation

was-cve20135414-priv-escalation (87476) The risk level is classified as LowLow Risk

Description:

IBM WebSphere Application Server could allow existing users to gain elevated privileges on the system caused by incorrect Administration Security roles being assigned after migration from version 6.1 or later.

NOTE: If a migration from WebSphere Application Server Version 6.1 or later has already been performed, all users designated with "adminsecmanager" (Administrative Security Manager) role need to be evaluated to determine if they should have both "admin" role and "adminsecmanager" role. Some users may not need both designations and the privileges should be removed accordingly.
