Technical details

A stack-based buffer overflow vulnerability exists in the Tenda BE12 Pro router firmware version 16.03.66.23. The flaw is located in the fromSetIpBind function within the /goform/SetIpBind endpoint, where the user-controlled 'page' parameter is processed using the unsafe sprintf function. Because the destination buffer 's' is fixed at 256 bytes and lacks length validation, an attacker can provide an oversized input to overwrite adjacent stack memory. This can be exploited remotely to achieve arbitrary code execution or a Denial of Service (DoS) by crashing the web server process. While some metrics suggest low privileges are required, a public PoC demonstrates the vulnerability being triggered via unauthenticated POST requests.
