Technical details
An OS command injection vulnerability exists in the 'webs' binary of the Edimax EW-7438RPn Wi-Fi extender (firmware versions up to 1.31). The flaw is located within the 'formWpsStart' function in the '/goform/formWpsStart' endpoint. The application fails to properly sanitize the 'pinCode' POST parameter before passing it to a system shell. A remote attacker with low privileges (authenticated access) can exploit this by injecting shell commands (e.g., using backticks) into the pinCode field. Successful exploitation allows for arbitrary code execution on the underlying operating system, such as starting a telnet daemon for persistent remote access. As of the advisory date, the vendor has not responded to disclosure attempts.
