PAN-OS: Authenticated Remote Code Execution (RCE) in Panorama

Overview

A remote code execution (RCE) vulnerability in Palo Alto Networks PAN-OS® software on Panorama enables an authenticated administrator with network access to execute arbitrary code with root privileges.

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 recommended  best 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 .
