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.
CVSS Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/AU:N/R:U/V:D/RE:M/U:Amber
CVSS Score: 6.1
The risk is highest when you allow access to the management interface from external IP addresses on the internet. Our recommendation is to remediate as soon as possible.

CVSS Score: 5.7
You can reduce the risk of exploitation by restricting access to a jump box that is the only system allowed to access the management interface. This will ensure that attacks can succeed only if they obtain privileged access through those specified IP addresses.
