Technical summary

The Tobit 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 through Rollout 524.
