Authenticated command execution via static-route parameters
Published Aug 20, 2025 · Updated Aug 20, 2025
OS command injection in Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 firmware allows remote authenticated users to execute commands. The addStaticRoute function in mod_form.so passes five static-route fields from /goform/addStaticRoute directly into an operating-system command without validating their contents. A valid management session is required, and successful exploitation starts attacker-chosen processes with the firmware's privileges, as demonstrated by launching a telnet shell.
