CVE-2024-11208Public exploitNetwork attack vector

Account access via post-logout session cookie reuse

Published Nov 14, 2024 · Updated Nov 14, 2024

Insufficient session expiration in Apereo CAS 6.6 allows remote attackers to retain account access through a session cookie after logout. The /login?service flow leaves the authentication session cookie valid after logout, so protected account requests continue to accept it. Exploitation requires a previously issued session cookie and permits continued access as the logged-out user, including access to protected account data.
