SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps security professionals identify and exploit Insecure Direct Object Reference (IDOR) vulnerabilities, a common flaw that allows unauthorized access to data.

Core Features & Use Cases

  • IDOR Discovery: Provides a comprehensive methodology for finding IDORs in web applications and APIs.
  • Bypass Techniques: Details methods to circumvent common IDOR protections.
  • Use Case: During a penetration test, you suspect an API endpoint might be vulnerable to IDOR. You would activate this skill to systematically test different ID values and parameter manipulations to gain unauthorized access to other users' data.

Quick Start

Use the idor skill to test the endpoint '/api/users/{id}/profile' for Insecure Direct Object References.

FAQPage Schema
How do I test for IDOR vulnerabilities in web applications and APIs?

To test for IDOR vulnerabilities, you systematically manipulate object reference parameters in web application endpoints and APIs to detect unauthorized data access. The process involves blind detection, mass testing, and analyzing access control flaws across various request endpoints.

What is an Insecure Direct Object Reference and how does parameter manipulation expose it?

An Insecure Direct Object Reference (IDOR) is an access control flaw where parameter manipulation allows unauthorized access to data. Attackers alter object references in web application URLs or API parameters to view or modify records belonging to other users.

Can I use IDOR testing techniques to bypass obfuscated IDs and access controls?

Yes, you can bypass obfuscated IDs and access controls by applying specific strategies to circumvent protections. Techniques include manipulating obfuscated identifiers and exploiting access control flaws to reveal hidden object references and gain unauthorized entry.

Does IDOR exploitation work with GraphQL, gRPC, and cloud-native object URLs?

IDOR exploitation works with GraphQL, gRPC, and cloud-native object URLs by targeting access control flaws across these protocols. It identifies unauthorized object references and parameter manipulation vectors specific to each architectural endpoint type.

What is the best way to discover blind IDOR vulnerabilities during penetration testing?

The best way to discover blind IDOR vulnerabilities is through systematic mass testing and parameter manipulation. This approach detects access control flaws by analyzing application responses to unauthorized object reference requests without direct visual confirmation.
