Senserva AI Opinion for CVE-2017-15944
Palo Alto Networks PAN-OS, the operating system on the firewalls guarding many networks, is the target here: multiple flaws chain together into unauthenticated remote code execution on the management plane. With a Critical CVSS 9.8, a 98% EPSS score, and confirmed exploitation (KEV 2022-08-18), a vulnerable firewall becomes the attacker's best vantage point rather than your defense. Compromising the security device itself is a worst-case outcome.
Do this: Confirm every PAN-OS firewall runs fixed software and that its management interface is unreachable from the internet.
