SYSTEM DOCUMENTATION & REQUIREMENTS

πŸ’‘ This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents unauthorized access to sensitive data by ensuring that API endpoints correctly verify user ownership of requested resources, mitigating Broken Object Level Authorization (BOLA) vulnerabilities.

Core Features & Use Cases

  • BOLA Detection: Identifies insecure direct object references in API endpoints.
  • Ownership Verification: Enforces that authenticated users can only access resources they own.
  • Use Case: When reviewing an API endpoint that fetches user-specific order details, this Skill ensures the code checks that the logged-in user is indeed the owner of the requested order ID before returning the data.

Quick Start

Use the bola-detector skill to review the attached file 'OrderService.java' for object-level authorization flaws.

FAQPage Schema
How do I detect BOLA vulnerabilities in API endpoints?β–Ό

To detect BOLA vulnerabilities in API endpoints, analyze code patterns across various languages and ORMs to verify that ownership checks are enforced at the query level before returning requested resources.

What is Broken Object Level Authorization and how does it expose data?β–Ό

Broken Object Level Authorization is an access control flaw where API endpoints fail to verify user ownership, allowing authenticated users to access sensitive data they do not own by insecurely referencing object IDs.

How do I prevent IDOR and enforce ownership verification in my API?β–Ό

Prevent IDOR by enforcing ownership verification checks directly at the database query level, ensuring your ORM modifies data fetches to automatically restrict results to resources owned by the authenticated user.

Does this BOLA detection approach work with different ORMs and programming languages?β–Ό

This BOLA detection approach works across various languages and ORMs by analyzing code patterns to enforce query-level ownership checks, ensuring authenticated users can only access their own resources regardless of the stack.

How does enforcing ownership checks at the query level mitigate OWASP API1:2023?β–Ό

Enforcing ownership checks at the query level mitigates OWASP API1:2023 by binding data access directly to the authenticated user identity within the database fetch, preventing unauthorized retrieval of requested object IDs.
