### 简要描述：
Destoon最新版本20131010补丁后，全版本继续注入
### 详细说明：
问题出在api/js.php这个漏洞，这个星期工作忙，结果别人提交了，官方补丁都出来了。
下载补丁，发现官方的修复比较马虎，没有理解漏洞的本质，分分钟绕过再次注入。
建议官方好好思考一下这个漏洞产生的根本原因。
### 漏洞证明：

strip_sql()过滤了union这个字符串，但是实际上是可以绕过的。
由于需要伪造referer，所以用php写的脚本进行漏洞利用，需要根据实际情况修改里面的路径。
POC里面host参数为域名，本机测试为localhost，ver参数为版本，里面写了3,4,5三个版本的利用代码。
