Palo Alto Networks PAN-OS 7.1.x < 8.1.14 / 8.0.x < 8.1.14 / 8.1.x < 8.1.14 / 9.0.x < 9.0.7 Vulnerability

High Nessus Plugin ID 136822

Synopsis

The remote PAN-OS host is affected by vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 8.1.14 or 8.0.x prior to 8.1.14 or 8.1.x prior to 8.1.14 or 9.0.x prior to 9.0.7. It is, therefore, affected by a vulnerability.

- 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. (CVE-2020-2011)

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 8.1.14 / 8.1.14 / 8.1.14 / 9.0.7 or later
