Name of the Vulnerable Software and Affected Versions IBM Security Identity Manager version 6.0.2

Description The issue is related to insufficient access controls in the Password Synchronization Plug-in of IBM Security Identity Manager, which could allow a remote attacker to gain unauthorized access to protected information. Specifically, an authenticated malicious user could change the passwords of other users in the Windows AD environment when the IBM Security Identity Manager Windows Password Synch Plug-in is deployed and configured.

Recommendations For IBM Security Identity Manager version 6.0.2, consider restricting access to the Windows Password Synch Plug-in to minimize the risk of exploitation until a patch is available. As a temporary workaround, limit the privileges of authenticated users to prevent them from changing passwords of other users in the Windows AD environment.
