CVE-2011-1321: The AuthCache purge implementation in the Security component in IBM WebSphere Application Server (WAS) 6.1....

The AuthCache purge implementation in the Security component in IBM WebSphere Application Server (WAS) 6.1.0.x before 6.1.0.37 and 7.x before 7.0.0.15 does not purge a user from the PlatformCredential cache, which might allow remote authenticated users to gain privileges by leveraging a group membership specified in an old RACF Object (aka RACO).

Security readout for executives and security teams

This is a legacy IBM WebSphere Application Server authorization flaw. In affected versions, removing or changing a user's group membership may not fully clear cached credentials, so an authenticated user could retain privileges tied to an older RACF group state. Exposure is likely limited to organizations still running IBM WebSphere Application Server 6.1 or 7 below the fixed levels, especially environments using RACF-backed group membership. The source bundle does not identify other affected products. Treat this as a targeted legacy-platform risk. It is not proven actively exploited in the provided sources, but stale authorization can undermine access governance where old WebSphere and RACF integrations remain in production. Mitigation focus: Upgrade WAS 6.1.0.x to 6.1.0.37 or later.; Upgrade WAS 7.x to 7.0.0.15 or later.; Review IBM PM24668 for vendor-specific fix guidance..
