BLUF: This walkthrough demonstrates exploiting a Django web app on the Hack The Box machine "IP" by chaining account registration logic flaws, IDOR, and SQL injection to achieve remote code execution. 0:05
Key Takeaways:
• The application uses a Django web app with a business logic vulnerability where account validation is bypassed via the "forgot password" functionality 0:05.
• A QR code-based login feature contains an Insecure Direct Object Reference (IDOR) vulnerability, allowing an attacker to impersonate any user, including the admin 0:24.
• Impersonating the admin grants access to the Django admin panel, which exposes a Microsoft SQL Server query interface vulnerable to SQL injection 0:33.
• Enumeration of the SQL injection point reveals the underlying database structure, facilitating further exploitation steps 0:37.
Closing Statement: The challenge highlights how multiple seemingly minor vulnerabilities can be chained to compromise a system's integrity and gain administrative control.

what's going on YouTube this is IP I'm doing freelancer from hack the box which is a nice hard machine it starts out with the D Jengo web app that has a business logic vulnerability within account registration when anyone registers an account they can't log in because it needs to be validated however if they use the forgot password functionality and successfully reset their password that validated flag will be set and they can log in to the app once in there's a magic link that lets people log in by scanning a QR code on their mobile device this has a idore vulnerability and let us impersonate any user so we impersonate the admin and that also lets us into the Django admin panel that has a way for us to execute Microsoft SQL queries we do a lot of enumeration and discover that we can imper…
