Buffer Overflow in Tenda G1 and G3 routers with firmware v15.11.0.17(9502)_CN allows remote attackers to execute arbitrary code via a crafted action/"portMappingIndex "request. This occurs because the “formDelPortMapping” function directly passes the parameter “portMappingIndex” to strcpy without limit.
