OliveTin Authentication Flaws

OliveTin gives access to predefined shell commands from a web interface. [CVSS 8.8 HIGH]

OliveTin prior to version 3000.11.1 fails to enforce view permission checks on dashboard and API endpoints, allowing authenticated users to enumerate action bindings, titles, IDs, icons, and argument metadata despite having restricted access. While command execution remains properly denied, this information disclosure enables attackers to map available actions and their configurations. Public exploit code exists for this medium-severity vulnerability, and a patch is available.

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. Public exploit code exists for this session management bypass.

OliveTin versions prior to 3000.11.1 contain an authentication bypass in RestartAction that allows authenticated users to execute shell commands beyond their assigned permissions. The vulnerability stems from improper request context handling that causes the system to fall back to guest user privileges, which may have broader access than the authenticated caller. Public exploit code exists for this medium-severity flaw that enables privilege escalation and unauthorized command execution.
