A vulnerability was identified in Edimax BR-6428NS 1.10. The impacted element is the function formWanTcpipSetup of the file /goform/formWanTcpipSetup of the component POST Request Handler. Such manipulation of the argument pppUserName leads to buffer overflow. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
