根据ZDI的漏洞描述:
The specific flaw exists in the RPC interface defined on port 2103 with
UUID fdb3a030-065f-11d1-bb9b-00a024ea5525. During the processing of
opnum 0x06 the service copies user-supplied information into a fixed
length stack buffer. Sending at least 300 bytes will trigger a stack
based buffer overflow due to a vulnerable wcscat() call. Exploitation
of this issue can result in arbitrary code execution.

漏洞是在UUID fdb3a030-065f-11d1-bb9b-00a024ea5525 的第6个调用引起的。最终通过一个 wcscat()的拷贝造成一个栈溢出.

查找了一下关于这个接口的一些定义
http://www.hsc.fr/ressources/articles/win_net_srv/msrpc_msmq.html

The Message Queuing service (msmq) runs RPC services, listening on the ncacn_ip_tcp transport. By default, the msmq services opens 4 TCP ports [81], including one or several of 2101/tcp, 2103/tcp, 2105/tcp and 2107/tcp.

The mqqm.dll (Windows NT MQ Queue Manager) DLL, loaded in the mqsvc.exe process, contains the following RPC services:

fdb3a030-065f-11d1-bb9b-00a024ea5525 v1.0
76d12b80-3467-11d3-91ff-0090272f9ea3 v1.0
1088a980-eae5-11d0-8d9b-00a02453c337 v1.0

41208ee0-e970-11d1-9b9e-00e02c064c39 v1.0

Table 4.49. qmcomm operations

             0x01             QMGetRemoteQueueName
             0x02             QMOpenRemoteQueue
             0x03             QMCloseRemoteQueueContext
             0x04             QMCreateRemoteCursor
             0x05             QMSendMessageInternal
             0x06             QMCreateObjectInternal

。。。。。。

事实上,这个服务运行在2101、2103、2105、2107端口,根据我后来的结果可以看到,这些端口都能够直接溢出

这个漏洞被微软标记为important,因为在2003偷偷修复了,在xp和2000 professional版本上,这个漏洞利用时候需要验证用户密码,只有在2000 server上,才能够无须身份验证的触发溢出。

Windows默认是没有装这个服务的,要安装这个服务可以在添加删除程序里,选择添加windows组件。

如果是英文版的系统,那么这里可能叫做 Message Queuing

安装完之后,可以通过 net start msmq 来启动服务。

服务的进程是 mqsvc.exe, 而服务是在 mqqm.dll 中,所以我们可以反汇编这个dll文件

用IDA反汇编mqqm.dll后,用mida插件逆向出RPC调用

导出IDL文件后,可以看到函数结构如下:3

/* opcode: 0x06, address: 0x613B5F03 */

long _QMCreateObjectInternal (
[in] long arg_1,
[in][string] wchar_t * arg_2,
[in][range(0,524288)] long arg_3,
[in][unique][size_is(arg_3)] char * arg_4,
[in][range(1,128)] long arg_5,
[in][size_is(arg_5)] long arg_6[],
[in][size_is(arg_5)] struct struct_4 arg_7[]
);

这个函数结构暂时先不管他,也可以自己重新构造了一个IDL文件.

通过IDA看 _QMCreateObjectInternal 函数,没过多久就看出了问题所在

在 QMCreatePrivateQueue 中的 ReplaceDNSNameWithNetBiosName 中,没有对输入进行充分检查,wcscat()导致了一个栈溢出。

; int __cdecl ReplaceDNSNameWithNetBiosName(wchar_t *Str, wchar_t *Dest)
[email protected]@[email protected] proc near

Str= dword ptr 4
Dest= dword ptr 8

push esi
push 5Ch ; Ch
push [esp+8+Str] ; Str
call ds:__imp__wcschr
pop ecx
mov esi, eax
pop ecx
push [email protected]@3PAGA ; Source
push [esp+8+Dest] ; Dest
call ds:__imp__wcscpy
pop ecx
pop ecx
push esi ; Source
push [esp+8+Dest] ; Dest
call ds:__imp__wcscat // 溢出
pop ecx
pop ecx
pop esi
retn
[email protected]@[email protected] endp

伪代码:

wchar_t *__cdecl ReplaceDNSNameWithNetBiosName(wchar_t *Str, wchar_t *Dest)
{
wchar_t *v3; // [email protected]

v3 = _wcschr(Str, 0x5Cu);
_wcscpy(Dest, g_szMachineName);
return _wcscat(Dest, v3);
}

这里我们后面再回过头来看。

那么,函数调用是这样的:

_QMCreateObjectInternal
|---------------QMCreatePrivateQueue
|-------------------ReplaceDNSNameWithNetBiosName

_QMCreateObjectInternal的伪代码为:

signed int __thiscall QMCreateObjectInternal(struct _RTL_CRITICAL_SECTION *this, RPC_BINDING_HANDLE Binding, unsigned int Type, wchar_t *Str, int a5, int a6, int a7, int a8, int a9)
{
__int32 v10; // [email protected]
__int32 v11; // [email protected]
int v12; // [email protected]
struct _RTL_CRITICAL_SECTION *v13; // [sp+4h] [bp-10h]@1
int v14; // [sp+10h] [bp-4h]@4

v13 = this;
if ( a5 && !a6 )
{
LogMsgHR(-1072824314, off_6B27271C, 0x125u);
return -1072824314;
}
v13 = &qmcmd_cs;
EnterCriticalSection(&qmcmd_cs);
v14 = 0;
if ( Type == 1 )
{
v12 = 1;
goto LABEL_14;
}
if ( Type == 2 )
{
Type = 0;
v11 = I_RpcBindingInqTransportType(Binding, &Type);
if ( v11 )
goto LABEL_20;
if ( Type == 4 )
{
v12 = 0;
LABEL_14:
v10 = CQPrivate__QMCreatePrivateQueue(Str, a5, a6, a7, a8, a9, v12);
goto LABEL_15;
}
if ( v11 )
LABEL_20:
LogMsgRPCStatus(v11, off_6B27271C, 0x28u);
LeaveCriticalSection(&qmcmd_cs);
return -1072824283;
}
v10 = -1072824319;
LABEL_15:
if ( v10 < 0 )
LogMsgHR(v10, off_6B27271C, 0x32u);
LeaveCriticalSection(&qmcmd_cs);
return v10;
}

============= 这是华丽的分割线 ================

首先要调用到 QMCreatePrivateQueue .

我们看到以下是依次是 _QMCreateObjectInternal的六个参数
Type= dword ptr 0Ch
Str= dword ptr 10h
arg_C= dword ptr 14h
arg_10= dword ptr 18h
arg_14= dword ptr 1Ch
arg_18= dword ptr 20h
arg_1C= dword ptr 24h

看以下代码片段

loc_6B22555B: ; CCriticalSection qmcmd_cs
mov esi, offset [email protected]@[email protected]@A
push esi ; lpCriticalSection
mov [ebp+var_10], esi
call ds:[email protected] ; EnterCriticalSection(x)
mov eax, [ebp+Type]
mov [ebp+var_4], ebx
dec eax
jz short loc_6B2255C1

在代码中,如果eax为1,dec eax后条件为真,会跳转到QMCreatePrivateQueue 去执行

而eax是由mov eax, [ebp+Type]传入的

所以要让流程走到QMCreatePrivateQueue
_QMCreateObjectInternal的第一个参数必须是为0x00000001

以下是 QMCreatePrivateQueue的调用

loc_6B2255C3: ; int
push [ebp+arg_1C]
mov ecx, offset [email protected]@[email protected]@A ; CQPrivate g_QPrivate
push [ebp+arg_18] ; int
push [ebp+arg_14] ; int
push [ebp+arg_10] ; int
push [ebp+arg_C] ; int
push [ebp+Str] ; Str
call [email protected]@@QAEJPBGKPAXKQAKQAUtagPROPVARIANT@@[email protected] ; CQPrivate::QMCreatePrivateQueue(ushort const *,ulong,void *,ulong,ulong * const,tagPROPVARIANT * const,int)

实际上,我们在后面可以看到,漏洞是由于QMCreatePrivateQueue的第一个参数,也就是_QMCreateObjectInternal的第二个参数所造成的。

进入QMCreatePrivateQueue 之后,我们要调用到 ReplaceDNSNameWithNetBiosName.
以下是代码片段

.text:6B2178A9 mov eax, offset sub_6B25BE64
.text:6B2178AE call __EH_prolog
.text:6B2178B3 sub esp, 138h
.text:6B2178B9 push ebx
.text:6B2178BA push esi
.text:6B2178BB mov esi, [ebp+8]
.text:6B2178BE lea eax, [ebp-1Ch]
.text:6B2178C1 push edi
.text:6B2178C2 push eax ; int
.text:6B2178C3 mov [ebp-18h], ecx
.text:6B2178C6 push esi ; Source
.text:6B2178C7 call [email protected]@[email protected] ; IsPathnameForLocalMachine(ushort const *,int *)
.text:6B2178CC xor ebx, ebx ; ebx 清0
.text:6B2178CE pop ecx
.text:6B2178CF cmp eax, ebx ; 比较ispath函数的返回值
.text:6B2178D1 pop ecx
.text:6B2178D2 jnz short loc_6B2178EC ; 这里有个判断

.text:6B2178EC cmp [ebp-1Ch], ebx ; 这里有个判断
.text:6B2178EF jz short loc_6B217906
.text:6B2178F1 lea eax, [ebp-144h] ; 在栈上
.text:6B2178F7 push eax ; Dest
.text:6B2178F8 push esi ; Str 我们传入的参数
.text:6B2178F9 call [email protected]@[email protected] ; ReplaceDNSNameWithNetBiosName(ushort const *,ushort *)

========== 这是聪明的分割线 ============

要走到 ReplaceDNSNameWithNetBiosName ,就需要先绕过 IsPathnameForLocalMachine 这个函数。 我在绕过这个函数上走了很多弯路,花了许多功夫。

看看IsPathnameForLocalMachine函数:

中间分析过程很多,这里我就拿重要的说

mov eax, offset sub_6B25D54C
call __EH_prolog
sub esp, 204h
push ebx
push esi
lea eax, [ebp+String1]
push edi
push eax ; Dest
push [ebp+Source] ; Source
call [email protected]@[email protected] ; ExtractMachineName(ushort const *,ushort *)
mov eax, [ebp+arg_4]
pop ecx
pop ecx
mov esi, ds:[email protected] ; CompareStringW(x,x,x,x,x,x)
and dword ptr [eax], 0
push 0FFFFFFFFh ; cchCount2
push [email protected]@3PAGA ; lpString2
lea eax, [ebp+String1]
mov edi, 800h
push 0FFFFFFFFh ; cchCount1
push eax ; lpString1
push 1 ; dwCmpFlags
push edi ; Locale
call esi ; CompareStringW(x,x,x,x,x,x) ; CompareStringW(x,x,x,x,x,x)
dec eax
dec eax
jnz short loc_6B2344E9

ExtractMachineName(ushort const *,ushort *) 这个函数把\x5c 就是斜杠前的名字,就是机器名拷贝到某处,所以我们的传入参数里要有斜杠。

然后CompareStringW(x,x,x,x,x,x) 函数,把我们传入的斜杠前的那部分和 机器名比较,这里机器名是通过
push [email protected]@3PAGA ; lpString2
取得的,所以是一个定值。

对比完后,我们要让返回值不能为2,因为要跳转到下面的地方:

loc_6B2344E9:
lea eax, [ebp+String1]
push 2Eh ; Ch
push eax ; Str
call ds:__imp__wcschr
pop ecx
test eax, eax
pop ecx
jz loc_6B2345DD

这里会把刚才斜杠前的那部分拿来比较,看中间有没有点,我们要让跳转条件非真,所以我们的传入参数中要带一个“.” 就是\x2e

然后我们控制流程来到

push [email protected]@3PAGA ; Str
mov ebx, ds:__imp__wcslen
call ebx ; __imp__wcslen
pop ecx
push eax ; cchCount2
mov eax, [email protected]@3PAGA ; ushort * g_szMachineName
push eax ; lpString2
push eax ; Str
call ebx ; __imp__wcslen
pop ecx
push eax ; cchCount1
lea eax, [ebp+String1]
push eax ; lpString1
push 1 ; dwCmpFlags
push edi ; Locale
call esi ; CompareStringW(x,x,x,x,x,x) ; CompareStringW(x,x,x,x,x,x)
dec eax
dec eax
jnz loc_6B2345DD

这里再次把机器名和我们传入的参数比较了一次, 这时候要让跳转条件不成立

流程继续走到

.text:6B234531 push [email protected]@3PAGA ; Str
.text:6B234537 call ebx ; __imp__wcslen
.text:6B234539 cmp [ebp+eax*2+String1], 2Eh
.text:6B234542 pop ecx
.text:6B234543 jnz loc_6B2345DD
.text:6B234549 mov eax, [email protected]@[email protected]@@A ; AP<ushort> g_szComputerDnsName
.text:6B23454E test eax, eax
.text:6B234550 jz short loc_6B234570
.text:6B234552 lea ecx, [ebp+String1]
.text:6B234558 push ecx ; Str2
.text:6B234559 push eax ; Str1
.text:6B23455A call ds:__imp___wcsicmp ;比较字符串
.text:6B234560 pop ecx
.text:6B234561 test eax, eax
.text:6B234563 pop ecx
.text:6B234564 jnz short loc_6B234570 ; 这里不能跳转
.text:6B234566 mov ecx, [ebp+arg_4]
.text:6B234569 push 1
.text:6B23456B pop eax
.text:6B23456C mov [ecx], eax
.text:6B23456E jmp short loc_6B2345DF

注意这里

mov eax, [email protected]@[email protected]@@A ; AP<ushort> g_szComputerDnsName
test eax, eax
jz short loc_6B234570

这个dns name是从机器中取的

.text:6B234552 lea ecx, [ebp+String1]
.text:6B234558 push ecx ; Str2
.text:6B234559 push eax ; Str1
.text:6B23455A call ds:__imp___wcsicmp

然后马上比较两个串是否相同。

根据我们的流程需要,最后要走到

mov ecx, [ebp+arg_4]
push 1
pop eax
mov [ecx], eax
jmp short loc_6B2345DF

然后这个天杀的 IsPathnameForLocalMachine 就总算返回为真了,而且我们同时绕过了以下两处的判断:

.text:6B2178CF cmp eax, ebx ; 比较ispath函数的返回值
.text:6B2178D1 pop ecx
.text:6B2178D2 jnz short loc_6B2178EC ; 这里有个判断

.text:6B2178EC cmp [ebp-1Ch], ebx ; 这里有个判断
.text:6B2178EF jz short loc_6B217906

从而让函数流程顺利的执行到了 ReplaceDNSNameWithNetBiosName

小结下绕过 IsPathnameForLocalMachine 的条件:
1. 要发送个 目标机器的dnsname 加上 一个斜杠 \
2. 要是unicode字符串发送dnsname

实际上从 ReplaceDNSNameWithNetBiosName 这个函数的名字也可以看出来,是要把DNS name替换为 机器名。

同时也可以看出来这个漏洞的利用条件: 需要知道目标机器的dnsname。
一般如果机器在域里面,那就是域后缀。
如下图:

我的机器名是: a-dda41398f44f4
DNS后缀是: .fuck

注意这个“.”很重要,在触发条件中是一定要的。

========= 这是要抓狂的分割线 =================

现在回过头来看 ReplaceDNSNameWithNetBiosName 的代码:

push esi
push 5Ch ; Ch
push [esp+8+Str] ; Str
call ds:__imp__wcschr
pop ecx
mov esi, eax
pop ecx
push [email protected]@3PAGA ; Source
push [esp+8+Dest] ; Dest
call ds:__imp__wcscpy
pop ecx
pop ecx
push esi ; Source
push [esp+8+Dest] ; Dest
call ds:__imp__wcscat

就是把 \ 后面的字符串,wcscat到 机器名后面, 而这个拷贝发生在栈上,没有做长度检查,发生了栈溢出。

最后我使用覆盖seh 的方法利用成功发送超过2000 bytes字节的stub,保证覆盖到栈底触发异常,然后call ebx执行shellcode

下面是一个装B的exploit,只适用于我的机器(机器名是a-dda41398f44f4 , dns 后缀是.fuck ),如果你要修改,需要考虑到机器名的不同带来的影响,要重新计算payload长度值. 为啥说这是装B的exploit呢,因为明明有更清晰的exploit写法我不写,要写个可以忽悠很多人的。所以说大家要是以前看到过这种exploit写法又看不懂,那不要灰心,那个人只是和我一样在装B而已!

Exploit运行效果:

Shellcode 使用exitthread退出线程,则可以反复溢出,如果使用seh退出,则会反复执行你的shellcode

======== 这是装B的分割线 ===============
