Course

This course offers a comprehensive examination of exploiting Insecure Direct Object Reference (IDOR) vulnerabilities using a simple Rails application. Initially, you will learn how an attacker can retrieve user passwords and crack them to gain access to the application. The course then guides you through bypassing Multi-Factor Authentication by exploiting the communication between the main application and the MFA backend service. Finally, you will discover how to gain code execution by manipulating file paths and leveraging insecure file handling methods in Ruby.

The course is divided into three main steps: finding the IDOR vulnerability to retrieve and crack user passwords, bypassing the Multi-Factor Authentication, and gaining code execution on the server. Each section provides clear, practical examples to illustrate the techniques used by attackers and how these vulnerabilities can be chained together to escalate access. By the end of the course, you will have a deep understanding of IDOR exploitation and the importance of securing web applications against such attacks.
