Summary
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, an authentication context confusion vulnerability in RestartAction allows a low‑privileged authenticated user to execute actions they are not permitted to run. RestartAction constructs a new internal connect.Request without preserving the original caller’s authentication headers or cookies. When this synthetic request is passed to StartAction, the authentication resolver falls back to the guest user. If the guest account has broader permissions than the authenticated caller, this results in privilege escalation and unauthorized command execution. This vulnerability allows a low‑privileged authenticated user to bypass ACL restrictions and execute arbitrary configured shell actions. This issue has been patched in version 3000.11.1.
