Unauthenticated persistent shutdown via internalRestart endpoint
Published Aug 7, 2026 · Updated Aug 7, 2026
Improper access control in TeamDavid Webbox through Rollout 524 allows remote attackers to shut down the service via /internalRestart. The endpoint omits authentication and invokes shutdown logic instead of restarting the service. A single Internet-reachable request leaves Webbox offline until an administrator manually starts it, interrupting web access without altering data.
