PHP2Shell update: attackers now hitting Palo Alto Networks firewalls through their internet-facing management pages
Palo Alto Networks warned on Wednesday that attackers are exploiting the PHP2Shell flaws (CVE-2026-109618 and CVE-2026-109619) against its firewall management interfaces that are exposed to the internet. It comes days after Israeli security firm Dream said a suspected China-linked attacker had combined PHP2Shell with a Linux kernel bug called Fragnesia (CVE-2026-46300) to take full control of 25 servers across the US, Japan, Taiwan and South Korea, including three in a US government-affiliated network, all running a large vendor's firewall software. CISA has added Fragnesia to its must-patch list and given US federal agencies until 31 October to fix it. Some PAN-OS fixes are still due on 29 and 30 October.
Why it matters: Firewalls are meant to keep attackers out, so a hacked one gives them a foothold inside the network. Palo Alto says no special settings are needed to be at risk, and the danger is greatest when the management page can be reached from the internet. Admins should install the fixed PAN-OS versions as soon as they are out, restrict management access to trusted internal addresses only, and follow Palo Alto's interim mitigations where a fix is not yet available.
