Add User Account with Admin Privilege without Login & Local File Inclusion

We can create user and give admin privilege to user which we have made without login. Because this app does not check the session on this request. We can download another file with change value on filename parameter and also we can send this request without login.

Mitigation:

Ensure that the application is properly validating user input and session tokens.
