API Security Misconfiguration Scanner

Identifies security misconfigurations in API implementations.

What is API Security Misconfiguration?

API Security Misconfiguration testing identifies insecure default settings, missing security headers, exposed debug information, overly permissive CORS, and improper error handling. These misconfigurations often exist because secure defaults weren't applied or development settings reached production.

Why is This Important?

Misconfigurations are easy to exploit and often provide attackers with significant information or access. Debug endpoints expose internals, verbose errors reveal stack traces, and misconfigured CORS enables cross-origin attacks. These issues are prevalent and easily automated.

How It Works

1. API Discovery

Automatically discovers API endpoints, methods, parameters, and authentication mechanisms from documentation or traffic.

2. Security Testing

Tests for OWASP API Top 10 vulnerabilities including broken authentication, excessive data exposure, and injection flaws.

3. Compliance Validation

Validates API security against industry standards with detailed findings and remediation guidance.

Key Capabilities

Complete API security coverage aligned with OWASP API Security Top 10 and industry best practices.

  • Automatic API endpoint discovery
  • Authentication and authorization testing
  • Rate limiting and resource exhaustion checks
  • Data exposure and sensitive info detection
  • API versioning and deprecation analysis

Frequently Asked Questions

What API misconfigurations should I look for?

Check for: debug mode enabled, verbose error messages with stack traces, exposed API documentation in production, overly permissive CORS (Access-Control-Allow-Origin: *), missing security headers, default credentials, and unnecessary HTTP methods enabled.

How do I test for API misconfiguration?

Testing: check response headers for security headers, trigger errors and examine messages, try OPTIONS and TRACE methods, test CORS from unauthorized origins, look for /debug, /admin, /swagger endpoints, and review configuration against security baselines.

What information do misconfigurations leak?

Leaked information: internal paths and file structure, database details in errors, framework and version information, server configurations, internal IP addresses, and development credentials or API keys.

How do I prevent API misconfiguration?

Prevention: use hardened production configurations, implement infrastructure-as-code with security reviews, disable debug modes in production, configure restrictive CORS, implement proper error handling, remove development endpoints, and conduct regular configuration audits.
