### 简要描述：
骑士CMS某接口2处SQL盲注#2(官网demo测试)
### 详细说明：
手机客户端2处接口存在SQL注入，SELECT注入无关键字过滤,理论上可以获取任意数据。
0x01: http://demo.74cms.com/android/jobs.php
=========================================================
对应代码：
```
14 if (!empty($aset['displayorder']))
15 {
16 $arr=explode('>',$aset['displayorder']);
17 $arr[1]=preg_match('/asc|desc/',$arr[1])?$arr[1]:"desc";
18 if ($arr[0]=="rtime")
19 {
20 $orderbysql=" ORDER BY refreshtime {$arr[1]}";
21 $jobstable=table('jobs_search_rtime');
22 }
```
displayorder参数过滤不正确导致SQL注入。
"displayorder":"rtime> limit 1 #desc"返回一行数据：
```
