Summary

Palo Alto Networks PAN-OS contains PHP2Shell vulnerabilities that affect Siemens RUGGEDCOM APE1808 industrial firewall appliances. The vulnerabilities exist in PAN-OS versions 10.2, 11.1, 11.2, 12.1, and 12.2 on these devices. The issues allow unauthenticated remote code execution on affected appliances. Customers should apply security updates from Palo Alto Networks and implement workarounds as recommended in their upstream security notifications.

What this means
What could happen
An attacker could execute arbitrary code on the RUGGEDCOM APE1808 firewall appliance, allowing them to bypass security controls, intercept network traffic, or disrupt communications between your facility network and remote sites. This could halt remote monitoring, access control, or emergency response capabilities.
Who's at risk
Organizations operating Siemens RUGGEDCOM APE1808 industrial firewalls, particularly those in manufacturing, utility, and critical infrastructure sectors that rely on these devices for perimeter security, network segmentation, or remote access control.
How it could be exploited
An attacker could send a specially crafted network request to the PAN-OS web interface on the RUGGEDCOM APE1808. The PHP2Shell vulnerability allows unauthenticated code execution, giving the attacker direct control over the device without needing valid credentials or prior system access.
Prerequisites
  • Network access to the PAN-OS web interface on the RUGGEDCOM APE1808 (typically port 443)
  • No authentication required
