开放了80和8089的http服务
FlatPress框架试了一些弱口令都登录失败了，然后耗费3小时试了很多漏洞，最后看了下hints，没想到密码是password，，，，
使用admin/password成功登录系统，那就可以用exp了
上传shell后访问即可，php前面貌似得加上GIT89a，不然没法上传
成功RCE
反弹shell
常规信息收集发现可以无密码sudo执行apt-get
常规sudo提权：https://gtfobins.github.io/gtfobins/apt-get/#sudo
sudo apt-get changelog apt
!/bin/sh
拿到proof
