首先扫描目标有哪些开放的端口:

# nmap -sV -A -sC -p- 192.168.140.164

Nmap done: 1 IP address (1 host up) scanned in 58.48 seconds

从扫描结果得知，有http服务、以及运行于高位端口（10000以及20000）的webmin服务，以及Samba服务。

首先分别登陆目标的80以及10000端口，发现80端口只有一个默认页面，而10000端口也就是网站管理接口需要用户名以及密码。

80端口页面虽然没有什么内容，但是页面源代码中发现如下信息：

<!--
don't worry no one will get here, it's safe to share with you my access. Its encrypted :)

++++++++++[>+>+++>+++++++>++++++++++<<<<-]>>++++++++++++++++.++++.>>+++++++++++++++++.----.<++++++++++.-----------.>-----------.++++.<<+.>-.--------.++++++++++++++++++++.<------------.>>---------.<<++++++.++++++.


-->

这应该是一串加密后的代码。经查询这是一种brainfuck加密方法：

Brainfuck是一种极小化的计算机语言，它是由Urban Müller在1993年创建的。由于fuck在英语中是脏话，这种语言有时被称为brainf*ck或brainf**k，甚至被简称为BF。
Ook与Brainfuck类似，也是用替换法。
特征：

brainfuck语言用> < + - . , [ ]八种符号来替换C语言的各种语法和命令：
例如： +++++++++++++++++.>+++++++++++++++++++++++++++++++++++++++++

 

到网站 https://www.splitbrain.org/services/ook 进行破解，得到解密后的信息：.2uqPEfj3D<P'a-3，应该是密码什么的,但是目前我们并没有得到用户名，因此用enum4linux尝试一下：

[+] Enumerating users using SID S-1-22-1 and logon username '', password ''
S-1-22-1-1000 Unix User\cyber (Local User)

 ================================================
|    Getting printer info for 192.168.140.164    |

从中发现了用户名cyber,因此用该用户名以及上面破解得到的密码，看能否登陆webmin,10000端口登陆并不成功，20000端口可以成功登陆。

在页面的地步（Cyber的左面，需要细心）发现了command_shell的功能,从而得到了user flag: 3mp!r3{You_Manage_To_Break_To_My_Secure_Access}
