## Technical details

A buffer overflow vulnerability exists in the /goform/formWlSiteSurvey handler where the ifname POST parameter is copied unsafely via strcpy() without bounds checking. An unauthenticated remote attacker can send a POST request with a crafted ifname value that exceeds the buffer size, causing a crash of the web server process and potentially enabling arbitrary code execution. The vulnerability affects firmware version 1.32 and is no longer supported by the vendor.
