Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root via an unvalidated multipart filename in the CBI FileUpload handler. Attackers can upload a valid OpenVPN configuration file through the VPN client config page with a filename containing $() shell substitution, which is passed through Lua %q to /bin/sh -c.
