  • After finding a way to register and login, On the dashboard source-code (view-source) I found a commented JavaScript code which was named as to-do which seems to be a password change functionality. By using the code I tried to make request to the endpoint POST /drpanel/drapi/editpassword.php with a username surprisingly the password of the account got updated and new password displayed on response.
  • So I tried to update the drAdmin password and it was updated and new password was shown in response

It is possible to edit the admins password (dradmin) from /drapi/editpassword as it's only looking for the username. Usernames can be enumerated when logging in as trying 'drAdmin' results in a different error. The username can also be found from FirstBlood v1.
