The Edimax BR-6208AC is a wireless router that allows remote users to configure network settings through a web interface. A buffer overflow in the /goform/formWlSiteSurvey endpoint allows unauthenticated remote attackers to crash the device or potentially execute arbitrary code by sending a malformed request with an oversized ifname parameter, causing service outages and potential device compromise.

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.
