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 8.1.x prior to 8.1.23 or 9.0.x prior to 9.0.16-hf or 9.1.x prior to 9.1.13-hf or 10.0.x prior to 10.0.10 or 10.1.x prior to 10.1.5-hf or 10.2.x prior to 10.2.1. It is, therefore, affected by a vulnerability.

- The Palo Alto Networks Product Security Assurance team is evaluating the OpenSSL infinite loop vulnerability (CVE-2022-0778) as it relates to our products. (CVE-2022-0778)

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 8.1.23 / 9.0.16-hf / 9.1.13-hf / 10.0.10 / 10.1.5-hf / 10.2.1 or later

How to Run

Here is how to run the Palo Alto Networks PAN-OS 8.1.x < 8.1.23 / 9.0.x < 9.0.16-hf / 9.1.x < 9.1.13-hf / 10.0.x < 10.0.10 / 10.1.x < 10.1.5-hf / 10.2.x < 10.2.1 Vulnerability as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Palo Alto Local Security Checks plugin family.
On the right side table select Palo Alto Networks PAN-OS 8.1.x < 8.1.23 / 9.0.x < 9.0.16-hf / 9.1.x < 9.1.13-hf / 10.0.x < 10.0.10 / 10.1.x < 10.1.5-hf / 10.2.x < 10.2.1 Vulnerability plugin ID 159362.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl palo_alto_CVE-2022-0778.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a palo_alto_CVE-2022-0778.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - palo_alto_CVE-2022-0778.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state palo_alto_CVE-2022-0778.nasl -t <IP/HOST>

Go back to menu.
