Palo Alto Networks PAN-OS 11.2.x < 11.2.10 / 12.1.x < 12.1.4 Vulnerability

high Nessus Plugin ID 298673

Synopsis

The remote PAN-OS host is affected by a vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 11.2.x prior to 11.2.10 or 12.1.x prior to 12.1.4. It is, therefore, affected by a vulnerability.

 A denial-of-service (DoS) vulnerability in the Advanced DNS Security (ADNS) feature of Palo Alto Networks PAN-OS software enables an unauthenticated attacker to initiate system reboots using a maliciously crafted packet. Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode.

 Cloud NGFW and Prisma Access are not impacted by this vulnerability.


Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PAN-OS 11.2.10 / 12.1.4 or later
