CVE-2026-54213 affects Tobit TeamDavid Webbox before Rollout 528. A publicly reachable Webbox administrative restart function lacks authentication and, contrary to its intended behavior, terminates the web-server service rather than restarting it. The service remains unavailable until an administrator manually restores it. Rollout 528 disables the affected functionality by default.
