CVE-2026-108894: Linksys E1700 OS command injection in static route handler

CVE-2026-108894 · Severity: critical · CVSS 9.9 · Published 2026-10-12

The Linksys E1700 router's static route configuration feature allows unauthenticated remote attackers to inject arbitrary operating system commands by manipulating route parameters. An attacker can exploit this to execute commands with root privileges, gain remote shell access, and take full control of the device and the home network it protects.

Technical details

The addStaticRoute function in the Static Route Handler component (/goform/addStaticRoute) fails to validate or sanitize user-supplied parameters (staticRoute_IP_setting, staticRoute_Netmask_setting, staticRoute_Gateway_setting, staticRoute_Metric_setting) before passing them to OS command execution. An unauthenticated remote attacker over the network can craft a POST request with shell metacharacters to execute arbitrary commands. The vulnerability allows complete device compromise and network access.
