Overview

A security automation tool that scans API endpoints to identify unauthenticated access vulnerabilities. It tests various HTTP methods and authentication schemes to detect APIs that may be exposing data without proper authentication.

Features

  • Multi-Method Testing: Tests GET, POST, PUT, DELETE methods
  • Authentication Bypass Detection: Identifies APIs accessible without proper auth
  • Token Validation: Tests with various authentication schemes (Bearer, Basic)
  • Automated Reporting: Generates detailed security reports
  • Email Notifications: Sends alerts for security findings
  • Concurrent Processing: Multi‑threaded scanning for efficiency

Prerequisites

  • Python 3.13+
  • Required Python packages (see requirements.txt)
  • Network access to target APIs
  • Email configuration for notifications

Installation

# Navigate to the solution directory
cd unauthenticated-apis-report

# Install dependencies
pip install -r requirements.txt

Configuration

API List Configuration

Create unauthenticated-api.json with your API endpoints:

{
  "data": [
    "https://api.example.com/v1/users",
    "https://api.example.com/v1/orders",
    "https://api.example.com/v1/admin"
  ]
}

Notification Setup

Configure email notifications in the Notification module for security alerts.

Usage

Basic Scan

python unauthenticated-api.py

Key Functions

  • get_api_list(): Loads API endpoints from configuration
  • check_authentication(api_url): Tests authentication for a specific endpoint
  • get_api_authentication(): Performs individual authentication tests
  • generate_password(): Creates random tokens for testing

Security Testing Methods

  1. No Authentication Headers – Tests if APIs respond successfully without any authentication.
  2. Invalid Token Testing – Tests with randomly generated tokens to identify weak validation.
  3. Authentication Scheme Testing
    • Bearer token validation
    • Basic authentication testing
    • Custom authorization headers
  4. HTTP Method Testing – Tests all common HTTP methods for each endpoint.

Report Output

The tool generates detailed reports, including:

  • Request/response details
  • Authentication status
  • Vulnerability findings
  • Remediation recommendations

Security Considerations

  • Ethical Use: Only scan APIs you own or have permission to test.
  • Rate Limiting: Implement delays to avoid overwhelming target systems.
  • Credential Security: Never use real credentials in testing.
  • Network Security: Run from secure, authorized networks only.

Integration

CI/CD Pipeline

Integrate into security scanning workflows:

# Add to pipeline
python unauthenticated-api.py --output-format json

Monitoring

Set up regular scans to monitor for new vulnerabilities.

Troubleshooting

Common Issues

  • Connection Timeouts: Increase timeout values for slow APIs.
  • Rate Limiting: Add delays between requests.
  • SSL Errors: Configure proper certificate validation.

Debug Mode

Enable verbose logging for detailed troubleshooting.

Contributing

  • Add new authentication schemes to test
  • Enhance reporting capabilities
  • Improve error handling
  • Add support for additional HTTP methods

Security Notice

This tool is designed for authorized security testing only. Ensure you have proper permission before scanning any APIs. Unauthorized testing may violate terms of service or applicable laws.
