Upgrade the TR3000 device firmware to version 2.5.42 or later, where this vulnerability is fixed. No other mitigations are specified or required once the device is updated.
Description
Cudy TR3000 devices before version 2.5.42 have a command injection vulnerability that allows authenticated administrators to execute arbitrary commands as root. This occurs via an unvalidated multipart filename in the CBI FileUpload handler, specifically when uploading an OpenVPN configuration file with a filename containing shell substitution characters. The vulnerability is fixed in version 2.5.42.
