Palo Alto: PHP2Shell is under active exploitation on internet-facing PAN-OS management interfaces. No special configuration required to be affected. Dream Research: chained with a kernel privilege-escalation to root; at least 25 firewalls in a pool of hundreds. Unit 42 verified the tooling. Default mgmt is not internet-facing; PAN says ~0.02% of the installed base was. A useful question: if the admin port is on the internet, what is the firewall still firewalling?
