CVE-2026-54213Tobit Laboratories AG TeamDavid's Webbox application exposes a functionality that allows the server to be
shut down when a specific endpoint (/internalRestart) is accessed. This
endpoint is accessible to unauthenticated users over the public
Internet. Instead of “restarting”, the server shuts completely down. As a
result, a remote attacker can trigger a persistent denial of service by
shutting down the web server without requiring authentication. Recovery
requires manual administrator intervention to restart the service. This issue affects TeamDavid before Rollout 528.
Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
