Details

OpenAM before 16.1.3 contains an improper authorization vulnerability that allows delegated administrators to destroy sessions outside their realms because realm checks use the requester's realm. Authenticated accounts holding the iplanet-am-session-destroy-sessions attribute can supply a target session identifier or handle to forcibly log out users in any realm.
