METHODOLOGY

Testing Process

1
Reconnaissance

API Discovery

Map all API endpoints, analyze OpenAPI/Swagger specs, identify authentication mechanisms, and document data flows.

  • Endpoint enumeration
  • Schema analysis
  • Auth flow mapping
  • Rate limit detection

Tools

PostmanSwagger UIBurp SuiteOWASP ZAP
2
Identity & Access

Authentication Testing

Test JWT implementation, OAuth flows, API key security, and session management for vulnerabilities.

  • JWT analysis
  • OAuth bypass
  • Token manipulation
  • Session fixation

Tools

3
Access Control

Authorization Testing

Test for BOLA, BFLA, mass assignment, and role-based access control bypasses across all endpoints.

  • IDOR testing
  • Privilege escalation
  • Mass assignment
  • Scope bypass

Tools

4
Input Security

Injection & Validation

Test for injection vulnerabilities, improper input validation, and business logic flaws in API endpoints.

  • SQL/NoSQL injection
  • GraphQL injection
  • Parameter tampering
  • Schema poisoning

Key Recommendation

Critical BOLA and authentication bypass issues require immediate remediation. API gateway hardening needed.

OWASP API TOP 10

Common Vulnerabilities

CRITICAL

Broken Object Level Authorization

Description

APIs expose endpoints that handle object identifiers without proper authorization validation. Attackers can access any user's data.

Technical Example

GET /api/users/12345/data with token for user 99999 | Response 200: Full user data returned

Remediation

Implement object-level authorization checks for every function that accesses data using user input.
