Technical details

A stack-based buffer overflow vulnerability exists in the Edimax BR-6428NS router version 1.10. The flaw is located within the 'formWanTcpipSetup' function in the '/goform/formWanTcpipSetup' component, which handles POST requests for WAN configuration. By manipulating the 'pppUserName' argument with an overly long string, a remote attacker with low privileges can trigger a memory corruption. This can result in arbitrary code execution or a denial of service (system crash). While the vendor was notified, no patch has been released, and public exploit code is reportedly available.
