Short explanation
A privilege bypass vulnerability in ZTNET prior to version 0.8.0 allows any authenticated low-privilege user to permanently deactivate arbitrary accounts, including administrators, via the /api/auth/user/invalidateUser endpoint.
This vulnerability allows attackers to lock administrators out, disrupt organization management, and deny access to any targeted user.
What should be done?
- Update the ZTNET application
- Follow vendor advisories and updates
Chain of evidence and sources
ZTNET 0.8.0 öncesi sürümlerde düşük yetkili kullanıcılar /api/auth/user/invalidateUser uç noktası üzerinden rastgele hesapları devre dışı bırakabilir.
Oturum denetimi sırasında session.user.id ile istemci tarafından sağlanan userId karşılaştırılmaz.
Show the technical text from the sources
ZTNET is a ZeroTier web UI for private controllers with multiuser and organization support. Prior to 0.8.0, any authenticated low-privilege user can permanently deactivate another account, including an administrator, through `POST /api/auth/user/invalidateUser`. In `src/pages/api/auth/user/invalidateUser.ts`, `getServerSession` checks only that a session exists and does not compare `session.user.id` with the client-supplied `userId`. Supplying a victim's `userId` and a `deviceId` for which no matching pair exists in `UserDevice` makes the handler set the target account's `isActive` to false. Login is then refused by `src/server/auth.ts` with `account-expired`. An attacker needs only a normal authenticated account and the victim's user ID, which may be obtainable from member lists, UI responses, logs, or other application metadata. This can lock administrators out, disrupt organization management, and deny access to any targeted user. This issue is fixed in version 0.8.0.
