Descriptions

An improper input validation vulnerability in the configuration daemon of Palo Alto Networks PAN-OS Panorama allows for a remote unauthenticated user to send a specifically crafted registration request to the device that causes the configuration service to crash. Repeated attempts to send this request result in denial of service to all PAN-OS Panorama services by restarting the device and putting it into maintenance mode. This issue affects: All versions of PAN-OS 7.1, PAN-OS 8.0; PAN-OS 8.1 versions earlier than 8.1.14; PAN-OS 9.0 versions earlier than 9.0.7; PAN-OS 9.1 versions earlier than 9.1.0.

Una vulnerabilidad de comprobación de entrada inapropiada en el demonio de configuración de Palo Alto Networks PAN-OS Panorama, permite a un usuario no autenticado remoto enviar una petición de registro específicamente diseñada hacia el dispositivo que causa que el servicio de configuración se bloquee. Repetidos intentos de enviar esta petición resultan en una denegación de servicio a todos los servicios de PAN-OS Panorama al reiniciar el dispositivo y ponerlo en modo de mantenimiento. Este problema afecta: Todas las versiones de PAN-OS 7.1, PAN-OS versión 8.0; PAN-OS versiones 8.1 anteriores a 8.1.14; PAN-OS versiones 9.0 anteriores a 9.0.7; PAN-OS versiones 9.1 anteriores a 9.1.0.
