Palo Alto Networks PAN-OS 7.0.x < 7.0.6 DHCP Packet Handling Dataplane DoS

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote host is affected by a denial of service vulnerability.

Description :

The version of Palo Alto Networks PAN-OS running on the remote host is
7.0.x < 7.0.6. It is, therefore, affected by a flaw in the firewall
functionality that is triggered when the firewall is configured as a
DHCP relay and it receives DHCP requests from a third-party client or
server that exceed the payload length specified in RFC-2132. An
unauthenticated, remote attacker can exploit this, via a crafted DHCP
packet, to cause the dataplane to restart, resulting in a denial of
service condition.

Risk factor :

Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 4.1
Public Exploit Available : true
