冲击波内幕点滴

作者：幽谷听泉

时间：2003-07-21 上午  人物：flashsky

发现了MS WINDOWS 2000 RPC拒绝服务与本地权限提升漏洞，并提供了完整的测试代码（见
附1）。

时间：2003-07-21 下午

微软实现了该漏洞，并发布该漏洞的公告：MS03-026：RPC接口任意代码可执行漏洞

时间：2003-07-22

微软发布了针对该漏洞的补丁程序

http://www.microsoft.com/china/technet/security/bulletin/MS03-026.asp

时间：2003-07-25 09:13  人物：flashsky

在国内的某著名论坛上发表了lsd rpc溢出全分析的文章，公布了实现rpc溢出漏洞的代码，
并详细讲述了基本原理（全文见附2）。

时间：2003-07-25到2003-07-28

在该论坛上众路英雄纷纷对flashsky提供的代码进行了修改

时间：2003-8-2  发现：Worm.SdBotRPC “流言”病毒

利用RPC的漏洞攻击网络中的计算机，攻击成功后向远端系统上的RPC系统服务所监听的端口
发送攻击代码，造成远端系统无法使用RPC服务或系统崩溃。

时间：2003-8-8　　发现：用VB编程语言编写的Worm.AutoRooter病毒

时间：2003-8-10　　发现了著名的冲击波（Worm.Blaster）病毒

时间：2003-08-15  美国媒体表态："冲击波"病毒涉嫌造成大停电

http://www.duba.net/c/2003/08/15/89250.shtml

时间：2003-08-18 出现了以虫制虫的良性蠕虫，我目前还不知道该病毒的名称，先借用网
上的名称 蠕虫2004，该病毒同样通过RPC的漏洞攻击网络中的计算机，蠕虫感染系统后会自
动清除系统中的冲击波病毒，然后根据系统语言版本是简体中文、繁体中文、韩文、英文以
及系统是Windows 2000还是Windows XP分别到微软站点下载相应的MS03-026补丁，并能检测
系统时间，如果系统时间是2004年，就自动清除自身。

LSD RPC 溢出漏洞之分析

转摘请注明作者和安全焦点

作者：FLASHSKY

作者单位：启明星辰积极防御实验室

WWW SITE：WWW.VENUSTECH.COM.CN WWW.XFOCUS.NET，WWW.SHOPSKY.COM

邮件：flashsky@xfocus.org,fangxing@venustech.com.cn,webmaster@shopsky.com

感谢BENJURRY做测试，翻译和代码的通用化处理。

邮件：benjurry@xfocus.org

 

LSD 的RPC溢出漏洞（MS03-26）其实包含了2个溢出漏洞，一个是本地的，一个是远程的。
他们都是由一个通用接口导致的。

导致问题的调用如下：

hr = CoGetInstanceFromFile(pServerInfo,NULL,0,CLSCTX_REMOTE_SERVER,STGM_READWRIT
E,L"C:\\1234561111111111111111111111111.doc",1,&qi);

这个调用的文件名参数（第5个参数，会引起溢出），当这个文件名超长的时候，会导致客
户端的本地溢出（在RPCSS中的GetPathForServer函数里只给了0X220堆栈的空间，但是是用
lstrcpyw进行拷贝的），这个我们在这里就不深入研究了(不过这个API先会检查本地文件是
否存在，在进行处理，因此由于建不了长文件，所以要利用这个溢出不能直接调用这个API
，而是构造好包信息以后直接调用LPC的函数，有兴趣的可以自己去试。),我们来讲解一下
远程的溢出。

在客户端给服务器传递这个参数的时候，会自动转化成如下格式：L“\\servername\c$\123
4561111111111111111111111111.doc"这样的形式传递给远程服务器，于是在远程服务器的
处理中会先取出servername名，但是这里没做检查，给定了0X20（默认NETBIOS名）大小的
空间，于是堆栈溢出产生了：

问题代码如下：

GetPathForServer：

.text:761543DA push ebp

.text:761543DB mov ebp, esp

.text:761543DD sub esp, 20h <-----0x20空间

.text:761543E0 mov eax, 

.text:761543E3 push ebx

.text:761543E4 push esi

.text:761543E5 mov esi, 

.text:761543E8 push edi

.text:761543E9 push 5Ch

.text:761543EB pop ebx

.text:761543EC mov , esi

.text:761543EE cmp , bx

.text:761543F1 mov edi, esi

.text:761543F3 jnz loc_761544BF

.text:761543F9 cmp , bx

.text:761543FD jnz loc_761544BF

.text:76154403 lea eax, 《-----------写入的地址，只有0X20

.text:76154406 push 0

.text:76154408 push eax

.text:76154409 push esi 〈----------------------我们传入的文件名参数

.text:7615440A call GetMachineName

。。。。。。。。。。。。。。。。。。。。。。。。。。 此函数返回的时候，溢出点生
效

 

GetMachineName:

.text:7614DB6F mov eax, 

.text:7614DB72 mov ecx, 

.text:7614DB75 lea edx, 

.text:7614DB78 mov ax, 

.text:7614DB7C cmp ax, 5Ch 〈-----------------只判断0X5C

.text:7614DB80 jz short loc_7614DB93

.text:7614DB82 sub edx, ecx

.text:7614DB84 

.text:7614DB84 loc_7614DB84: ; CODE XREF: sub_7614DA19+178j

.text:7614DB84 mov , ax 〈----------------写入上个只有0X20的空间，超过就溢出

.text:7614DB87 inc ecx

.text:7614DB88 inc ecx

.text:7614DB89 mov ax, 

.text:7614DB8D cmp ax, 5Ch

.text:7614DB91 jnz short loc_7614DB84

.text:7614DB93 

 

OK，我们现在就需要想法来利用这个漏洞，由于\\SERVERNAME是由系统自动生成的，我们只
能利用手工直接生成RPC的包来实现，另外SHELLCODE中不能包含0X5C，因为这样判断就是\\
SERVERNAME结束了。

下面就给出一个实现的代码，注意点如下：

1.由于RPCRT4，RPCSS中没有JMP ESP的代码，这里使用了OLE32.DLL中的，但是这可能是会
重定位的，大家测试的时候

需要再确定或自己找一个存在的JMP ESP的代脉，我的这是WIN2000+SP3上的地址且OLE32未
重定位情况下的。

2。这里使用了反向连接的SHELLCODE，需要先运行NC

3。程序中的SC的整体长度必须满足sizeof(sz)%16=12的关系，因为不是整数的话，整个包
的长度会有一些填充，那么

计算就不满足我这里给出的一个简单关系了，会导致RPC包的解析无效果。

4。在溢出返回前，返回地址后面的2个参数还会使用，所以需要保证是个内存可写空间地址
。

5，这里是直接使用堆栈溢出返回的，其实大家也可以尝试一下覆盖SEH，这里就不再多讲了
。

补丁机理：

补丁把远程和本地的溢出都补了，呵呵，这个这么有名的东西，我也懒得多说了。

 

补记：

由于缺乏更多的技术细节，搞这个从上星期五到现在终于才搞定，惭愧，不过值得庆幸的是
其间发现了RPC DCOM DOS的漏洞。先开始被本地溢出的迷惑了很久，怎么也无法远程进入这
个函数，最后偶然的一次，让我错误的看花了眼，再远程调用的时候，以为GETSERVERPATH
是存在本地溢出的GetPathForServer函数，，心中以为远程进入了GetPathForServer函数，
仔细的跟踪，这才发现问题所在。感谢所有关心和指导我的同志们。
