Palo Alto Networks Panorama PAN-OS < 6.0.1 Firmware Signature Verification Bypass Arbitrary Code Execution

high Nessus Plugin ID 86186

Language:

Synopsis

The remote host is affected by a firmware signature bypass vulnerability.

Description

The remote Panorama appliance is running a version of Palo Alto Networks PAN-OS prior to 6.0.1. It is, therefore, affected by a firmware signature bypass vulnerability due to a flaw in signature verification process that allows an attacker to execute arbitrary Python code within an image file before the signature is verified.
Exploitation of this issue requires convincing an administrator to install a file from a malicious source (e.g. social engineering, hosting on a phishing site, or a man-in-the-middle attack on a legitimate download).

Solution

Upgrade to Palo Alto Networks PAN-OS version 6.0.1 or later.
