An attacker with a previously stolen or captured session cookie can continue authenticating after logout, resulting in a post-logout authentication bypass.

MEDIUM 5.4EPSS 0.30%

Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

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.
