| Описание | We found an stack overflow vulnerability in Edimax extender with firmware which was released recently, allows remote attackers to crash the server.In the router's formWirelessTbl function, submit-url is directly passed by the attacker, If this part of the data is too long, it will cause the stack overflow, so we can control the submit-url to execute arbitrary code.
