用户有了，现在加一个字典或者社工库就可以跑密码了，不对，登录请求中怎么没有用户名和密码呢？
仔细看一下，用户名和密码使用js加密后添加到url中，不过程序员给出了解密算法，而且该开发人员写的加密没有混淆和轮换，明显明显没有深厚的密码学功底，不说了，上代码：

调用你们的加密算法，把密码和用户名加密，加到url中就可以不断爆破了
burp跑起来
跑啊
跑啊
跑啊
不对，ip被封了，密码只校验了两次，返回值是：
var login_result = { "stauts" : 0 , "block" : 1, "ip" : "127.0.0.1"}
试试添加个X-Forwarded-for 试试，发现第一次可以，再试还是被封，
所以后台封ip是从X-Forwarded-for中取值，而且每个ip登录错误次数到3次就会被封掉，账号、密码、waf都解决了，而且还没验证马，来个poc开跑：
