An OS command injection vulnerability in the Palo Alto Networks PAN-OS management interface exists when performing dynamic updates. This vulnerability enables a man-in-the-middle attacker to execute arbitrary OS commands to escalate privileges.

Work around:
Updating dynamic content from a local file will prevent exposure to this vulnerability until you are able to upgrade PAN-OS firewalls and Panorama to a fixed version. You can disable scheduled dynamic updates in the web interface.

Push content updates from Panorama to the managed firewalls until you are able to upgrade PAN-OS to a fixed version. The process of upgrading dynamic content on managed devices is referenced here:
