Senserva AI Opinion for CVE-2024-3400
This is an unauthenticated command injection in the PAN-OS GlobalProtect feature that hands attackers root on the firewall itself, meaning the security device becomes the entry point. Anyone running GlobalProtect on an internet-facing PAN-OS firewall is exposed, and it is already confirmed in CISA KEV and used in ransomware campaigns with a maxed CVSS 10.0 and 100 percent EPSS. Because the firewall is the perimeter, a compromise here gives adversaries a trusted foothold into everything behind it.
Do this: Apply the Palo Alto Networks PAN-OS fix or vendor mitigation for GlobalProtect immediately and inspect the firewall for signs of prior root-level compromise.
