Estado: ModificadaCrítica (9.8)—

D-link DIR-816 A2 v1.10 is affected by a remote code injection vulnerability. An HTTP request parameter can be used in command string construction in the handler function of the /goform/dir_setWanWifi, which can lead to command injection via shell metacharacters in the statuscheckpppoeuser parameter.
