IDOR Vulnerability Testing

Provide systematic methodologies for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications. This skill covers both database object references and static file references, detection techniques using parameter manipulation and enumeration, exploitation via Burp Suite, and remediation strategies for securing applications against unauthorized access. Occurs when applications reference database records via user-controllable parameters: Occurs when applications expose file paths or names that can be enumerated: Capture and analyze requests containing: Cause : Server-side access control is implemented Solution : Cause : Randomized identifiers reduce enumeration risk Solution : Cause : Application validates session against requested resource Solution : Cause : Application implements request throttling Solution : Cause : Response doesn't clearly indicate data ownership Solution : - Target Web Application : URL of application with user-specific resources - Multiple User Accounts : At least two test accounts to verify cross-user access - Burp Suite or Proxy Tool : Intercepting proxy for request manipulation - Authorization : Written permission for security testing - Understanding of Application Flow : Knowledge of how objects are referenced (IDs, filenames) - IDOR Vulnerability Report : Documentation of discovered access control bypasses -...
