0x01 前台SSRF漏洞
位于 /Application/Home/Controller/LoginController.class.php 控制器的otcurl方法存在curl_exec函数，且传参均可控，导致漏洞产生.

0x02 前台任意文件上传漏洞
位于 /Common/Common/function.php 中有一处文件上传的操作，且未有任何过滤，我们全局搜索一下调用该函数的文件.

0x03 前台SQL注入漏洞
需要前台用户登录权限
位于 /Home/Controller/MemberController.class.php 控制器中的 my_up_level 方法 通过$_GET传入变量$phone 并直接拼接进SQL语句，导致注入产生.
