简要描述：

骑士CMS某接口1处宽字节SQL盲注(官网demo测试)

详细说明：

手机客户端1处接口存在宽字节SQL注入，无关键字过滤,理论上可以获取任意数据。

http://demo.74cms.com/android/login.php


对应代码：

10      $username=addslashes($username);
  11      $password=addslashes($password);
  12      $username=iconv("utf-8",QISHI_DBCHARSET,$username);
  13      $password=iconv("utf-8",QISHI_DBCHARSET,$password);


$username经过iconv转换后直接进入了SQL,导致SQL注入。没有回显，只好时间延迟注入了。
0x01: "username": "%E9%8C%A6"返回数据库错误
