CVE-2026-0273: PAN-OS: Authenticated Admin Command Injection Vulnerability via CLI or Web UI (Severity: MEDIUM)

Published Jun 10, 2026
·
Updated

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 CLI or Web UI.

The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators and by restricting access to the management web 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 .

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.

  19. Configuration

    Enable Threat Prevention on the inbound traffic to management services.

    Palo Alto Networks firewall management interface inbound traffic Threat Prevention (enable) = enabled
  20. Compensating control

    Secure access to the management interface per the best practice deployment guidelines: decrypt inbound traffic to the management interface so the firewall can inspect it.

  21. Compensating control

    Replace the Certificate for Inbound Traffic Management.

  22. Compensating control

    Route incoming traffic for the MGT port through a DP port (for example, enable the management profile on a DP interface for management access).

  23. Compensating control

    Restrict management interface access to only trusted internal IP addresses; minimize CLI and management web exposure by limiting CLI access to a limited group of administrators and allowing management web access only from trusted internal IP addresses.

  24. Compensating control

    If you have a Threat Prevention subscription, block attacks for this vulnerability by enabling Threat IDs 510028 and 510029 (from Applications and Threats content version 9112-10102 and later).
