🌐 Web Security: HTTP Header Manipulation and Security Bypass
HTTP headers are fundamental components of web communication that control authentication, authorization, and access control mechanisms. Understanding how to manipulate these headers is crucial for security professionals to identify vulnerabilities in web applications that rely on client-provided header information for security decisions.
🎯 What You'll Learn
- ✓ HTTP header structure and functionality
- ✓ Common security-related HTTP headers
- ✓ Header manipulation techniques and tools
- ✓ Client-side security bypass methods
🔍 Challenge Overview
You are presented with SecurePortal, a web application that implements access control based on HTTP headers. The application appears to restrict access to certain areas, but experienced security researchers know that client-controlled headers can often be manipulated to bypass these restrictions.
