Descriptions

An insecure configuration of the appweb daemon of Palo Alto Networks PAN-OS 8.1 allows a remote unauthenticated user to send a specifically crafted request to the device that causes the appweb service to crash. Repeated attempts to send this request result in denial of service to all PAN-OS services by restarting the device and putting it into maintenance mode. This issue impacts all versions of PAN-OS 8.0, and PAN-OS 8.1 versions earlier than 8.1.16.

Una configuración no segura del demonio appweb de Palo Alto Networks PAN-OS versión 8.1, permite a un usuario remoto no autenticado enviar una petición específicamente diseñada al dispositivo que causa que el servicio appweb se bloquee. Los intentos repetidos de enviar esta petición resultan en la denegación de servicio para todos los servicios de PAN-OS al reiniciar el dispositivo y ponerlo en modo de mantenimiento. Este problema afecta a todas las Versiones PAN-OS 8.0 y a las Versiones PAN-OS 8.1 anteriores a 8.1.16.
