Elevated risk69th percentile - higher than 69% of all known CVEs
Summary
A command injection vulnerability in Palo Alto Networks PAN-OS software allows an authenticated administrator to bypass system restrictions and run arbitrary commands as root. The user must have access to the PAN-OS CLI or Web UI to exploit this issue.
Risk Assessment
The risk is significantly minimized when CLI access is restricted to a limited group of administrators and management web interface access is restricted to trusted internal IP addresses. This issue affects PA-Series, VM-Series firewalls, and Panorama (virtual and M-Series).
Recommendation
Restrict CLI and management web interface access to trusted IP addresses and a limited group of administrators. Apply updates provided by Palo Alto Networks.

Original NVD description (English source)
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.
