Palo Alto Networks PAN-OS 10.2.x / 11.1.x / 11.2.x / 12.1.x / 12.2.x Vulnerability

high Nessus Plugin ID 365665

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 a vulnerable version of 10.2.x, 11.1.x, 11.2.x, 12.1.x, or 12.2.x. It is, therefore, affected by a vulnerability.

 A command injection vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to bypass system restrictions and run arbitrary commands as a root user. To be able to exploit this issue, the user must have access to the PAN-OS management interface.


 The security risk posed by this issue is significantly minimized by restricting access to the management interface to only trusted internal IP addresses according to our recommendedbest practice deployment guidelines (https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the- management-access-of-your-palo/ba-p/464431).

 This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).

 Cloud NGFW and Prisma Access are not affected 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.
