OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, OliveTin does not revoke server-side sessions when a user logs out. Although the browser cookie is cleared, the corresponding session remains valid in server storage until expiry (default ≈ 1 year). An attacker with a previously stolen or captured session cookie can continue authenticating after logout, resulting in a post-logout authentication bypass. This is a session management flaw that violates expected logout semantics. This issue has been patched in version 3000.11.1.
AnalysisAI
OliveTin prior to version 3000.11.1 fails to invalidate server-side sessions upon user logout, allowing attackers with a stolen session cookie to maintain authenticated access even after the legitimate user logs out. The vulnerability persists because browser cookies are cleared while the corresponding server session remains valid for approximately one year by default. …
