Senserva AI Opinion for CVE-2019-1579
CVE-2019-1579 is a pre-authentication remote code execution flaw in PAN-OS that triggers only when the GlobalProtect Portal or Gateway interface is exposed, which means your internet-facing VPN appliances are the exact attack surface here. It carries Severity High (CVSS 8.1), sits on the CISA KEV list since 2022-01-10, and has been used in ransomware campaigns, so an exposed unpatched firewall is a direct path to full compromise. With a 46 percent EPSS score, active exploitation of remaining unpatched devices is a live concern.
Do this: Identify all PAN-OS firewalls with GlobalProtect Portal or Gateway enabled on internet-facing interfaces and apply the vendor patch immediately.
