The security risk posed by this issue is minimized when the management interface is restricted to only trusted internal IP addresses according to our recommended best practice deployment guidelines . 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 these vulnerabilities. Product Status Versions Affected Unaffected Cloud NGFW None All PAN-OS 12.2 = 12.2.4 PAN-OS 12.1 = 12.1.10-h2 PAN-OS 11.2 = 11.2.17 PAN-OS 11.1 = 11.1.16-h3 Prisma Access None All Required Configuration for Exposure No special configuration is required to be affected by this issue. Severity:LOW, Suggested Urgency:MODERATE The risk is highest when you allow access to the management interface from external IP addresses on the internet.
