title: PAN-OS: OS Command Injection Vulnerability When Performing Dynamic Updates
description: 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. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.20-h1; PAN-OS 9.0 versions earlier than PAN-OS 9.0.14-h3; PAN-OS 9.1 versions earlier than PAN-OS 9.1.11-h2; PAN-OS 10.0 versions earlier than PAN-OS 10.0.8; PAN-OS 10.1 versions earlier than PAN-OS 10.1.3. Prisma Access customers that have Prisma Access 2.1 Preferred or Prisma Access 2.1 Innovation firewalls are impacted by this issue.

exploits: Palo Alto Networks is not aware of any malicious exploitation of this issue.
solutions: This issue is fixed in PAN-OS 8.1.20-h1, PAN-OS 9.0.14-h3, PAN-OS 9.1.11-h2, PAN-OS 10.0.8, PAN-OS 10.1.3, and all later PAN-OS versions.
workarounds: You can disable scheduled dynamic updates for the firewall at 'Device Deployment > Dynamic Updates' in the web interface. Choosing not to receive dynamic updates will minimize your exposure to this vulnerability until you upgrade the PAN-OS firewall to a fixed version.
