API Vulnerability Testing

Test your API security with comprehensive vulnerability simulations that identify weaknesses in authentication, authorization, and data protection.

API Security Testing Features​

Authentication Testing​

Test authentication mechanisms:

  • Credential testing
  • Token security
  • Session management
  • MFA bypass attempts

Authorization Testing​

Validate access controls:

  • Role-based access
  • Resource permissions
  • Privilege escalation
  • Cross-tenant access

Injection Testing​

Test for injection flaws:

  • SQL injection
  • NoSQL injection
  • Command injection
  • LDAP injection

Data Exposure Testing​

Check data protection:

  • Sensitive data exposure
  • Excessive data returns
  • Debug information leakage
  • Error message details

API Vulnerability Categories​

OWASP API Top 10​

Test for common API vulnerabilities:

  1. Broken Object Level Authorization
  2. Broken Authentication
  3. Broken Object Property Level Authorization
  4. Unrestricted Resource Consumption
  5. Broken Function Level Authorization
  6. Unrestricted Access to Sensitive Business Flows
  7. Server Side Request Forgery
  8. Security Misconfiguration
  9. Improper Inventory Management
  10. Unsafe Consumption of APIs

Custom Tests​

Define organization-specific tests:

  • Business logic flaws
  • Custom authentication
  • Proprietary protocols
  • Internal APIs

Running API Tests​

Setting Up Tests​

  1. Navigate to Attack Simulation → API Vulnerabilities
  2. Click New Test
  3. Configure:
    • API endpoint(s)
    • Authentication
    • Test categories
    • Scope limits
  4. Review and execute

Target Configuration​

Define what to test:

  • API base URL
  • Endpoints to test
  • Authentication credentials
  • Rate limit considerations

Test Selection​

Choose test types:

  • Quick scan (common issues)
  • Full scan (comprehensive)
  • Custom selection
  • Compliance-focused

Test Results​

Common Findings​

Authentication Issues​

  • Weak token generation
  • Missing authentication
  • Insecure token storage
  • Session fixation

Authorization Flaws​

  • Horizontal privilege escalation
  • Vertical privilege escalation
  • Missing function-level checks
  • IDOR vulnerabilities

Data Exposure​

  • Sensitive data in responses
  • PII leakage
  • Debug endpoints exposed
  • Verbose error messages

Input Validation​

  • Missing input validation
  • Injection vulnerabilities
  • Type confusion
  • Buffer issues

Remediation​

Fix Guidance​

For each vulnerability:

  • Root cause explanation
  • Recommended fix
  • Code examples
  • Testing approach

Prioritization​

Fix order recommendations:

  • Critical first
  • High risk next
  • By endpoint importance
  • By exploitation ease

Verification​

Confirm fixes:

  • Re-test specific endpoints
  • Regression testing
  • Continuous testing

Best Practices​

  1. Test all APIs - Internal and external
  2. Regular testing - Continuous or scheduled
  3. Pre-production testing - Before deployment
  4. Authenticate properly - Use valid credentials for depth
  5. Monitor rate limits - Respect API limits
  6. Fix and verify - Close the loop on findings
