Technical details

A classic buffer overflow (CWE-120/CWE-119) exists in the Edimax EW-7478APC firmware version 1.04. The vulnerability is located within the formiNICSiteSurvey function in the /goform/formiNICSiteSurvey file, which handles POST requests. By manipulating the 'selSSID' argument, a remote attacker with low privileges can trigger a memory corruption. This can lead to arbitrary code execution or a denial of service (DoS) condition. Public exploit code is reportedly available, and the vendor has not responded to disclosure attempts.
