Technical details

A command injection vulnerability exists in the Edimax BR-6675nD router version 1.12. The flaw is located within the 'formWlanMP' function of the '/goform/formWlanMP' endpoint, which serves as a POST request handler. Multiple parameters, including 'ateFunc', 'ateGain', and 'ateRate', fail to properly neutralize special elements before they are used in system commands. A remote attacker with low privileges can exploit this by sending a malicious POST request to execute arbitrary commands on the underlying operating system. As of the disclosure date, the vendor has not provided a patch.
