Description

The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.20 or 9.0.x prior to 9.0.14 or 9.1.x prior to 9.1.9 or 10.0.x prior to 10.0.5. It is, therefore, affected by a vulnerability.

 - An improper handling of exceptional conditions vulnerability exists in the Palo Alto Networks PAN-OS dataplane that enables an unauthenticated network-based attacker to send specifically crafted traffic through the firewall that causes the 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.
