🔐 Can you access files that aren't meant for you?
This secure document management system thinks it can protect sensitive files with simple reference numbers. 📁 But experienced security researchers know that direct object references can be manipulated to access unauthorized resources! 🕵️ Master the art of parameter manipulation and discover how seemingly secure applications can leak sensitive information through predictable patterns. 🎯

🔍 Web Security: Insecure Direct Object Reference (IDOR)
Insecure Direct Object Reference (IDOR) vulnerabilities occur when applications expose internal object references (like database keys, file paths, or user IDs) without proper authorization checks. This fundamental security flaw allows attackers to access unauthorized resources by manipulating reference parameters.
🎯 What You'll Learn
- ✓ Understanding IDOR vulnerability patterns
- ✓ Parameter manipulation techniques
- ✓ Authorization bypass methods
- ✓ Web application enumeration
🔍 Challenge Overview
You are presented with SecureFiles, a document management system that allows users to access their personal files. The application uses direct object references to identify resources, but the authorization mechanism may have weaknesses that allow access to unauthorized documents.
