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

      "value": "La aplicación Webbox de TeamDavid de Tobit Laboratories AG expone una funcionalidad que permite apagar el servidor cuando se accede a un endpoint específico (/internalRestart). Este endpoint es accesible para usuarios no autenticados a través de Internet público. En lugar de ’reiniciar’, el servidor se apaga completamente. Como resultado, un atacante remoto puede desencadenar una denegación de servicio persistente al apagar el servidor web sin requerir autenticación. La recuperación requiere intervención manual del administrador para reiniciar el servicio. Este problema afecta a TeamDavid hasta el Rollout 524."
