Summary

A buffer overflow vulnerability has been identified in Tenda AC series routers, specifically through the web server ('httpd'). When handling POST requests containing the 'firewallEn' parameter, the software improperly utilizes this parameter in a strcpy function. This mishandling enables attackers to overflow the stack, allowing for the potential overwrite of critical return addresses within the function, thus posing a significant security risk.
