Deep dives
X-Correlation Injection Vulnerabilities
X-correlation IDs, frequently used in HTTP requests, can open up significant vulnerabilities in server-side architectures. These identifiers, which help trace requests across microservices, are often customizable and can be manipulated during their lifecycle in an application's backend. By exploiting these request headers, attackers can gain in-depth access to sensitive system processes, potentially allowing for injection attacks that lead to severe data breaches. The discussion emphasizes the need for rigorous validation of these identifiers to prevent unauthorized access and to ensure system integrity.
