You can familiarize yourself with the admin panel by logging in using the credentials administrator:admin. To solve the lab, log in using the credentials wiener:peter and exploit the flawed access controls to promote yourself to become an administrator. 🔗 Resources About Referer Header: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referer ✅ What to do ? 1. Log in using the admin credentials. 2. Browse to the admin panel, promote carlos, and send the HTTP request to Burp Repeater. 3. Open a private/incognito browser window, and log in with the non-admin credentials. 4. Browse to /admin-roles?username=carlos&action=upgrade and observe that the request is treated as unauthorized due to the absent Referer header. 5. Copy the non-admin user's session cookie into the existing Burp Repeater request, change the username to yours, and replay it.
