Technical details

A stack-based buffer overflow vulnerability exists in the Edimax BR-6478AC router version 1.23 within the POST request handler. The flaw is located in the 'formWanTcpipSetup' function in the '/goform/formWanTcpipSetup' file. By sending a specially crafted POST request with a manipulated 'pppUserName' argument, a remote attacker with low privileges can trigger the overflow. This can lead to arbitrary code execution or a system crash (denial of service). Public exploit code is reportedly available, increasing the risk of exploitation.
