AI System Penetration Test Results

​

Executive Summary

This document presents the findings from a comprehensive security assessment of the AI system implemented in the Astro application. The assessment included endpoint security tests, authentication bypass attempts, and web vulnerability scanning. Testing Date: March 17, 2025
Test Environment: Development
Test Coverage: AI API endpoints and web application security

​

Key Findings

• Endpoint Security: All 12 endpoint security tests failed, indicating potential issues with API endpoint implementation, authentication, or error handling
• Authentication Bypass: No successful authentication bypasses were detected across 55 test cases
• Web Vulnerabilities: 3 high-severity issues identified related to security headers, CORS configuration, and information disclosure

​

Risk Assessment

​

Detailed Findings

​

1. Endpoint Security Issues

​

1.1 API Endpoint Availability

All endpoint tests failed due to connection failures or timeouts, indicating the API endpoints might not be properly implemented or exposed. Affected Endpoints:

• /api/ai/completion (POST)
• /api/ai/usage (GET)

Recommendation:

• Verify API routes are correctly implemented and exposed
• Ensure the development server is running during tests
• Check for network configuration issues preventing access

​

1.2 Authentication Validation

Tests for authentication validation failed for both endpoints, indicating potential issues with the authentication middleware. Recommendation:

• Implement proper JWT or session-based authentication
• Add middleware to validate authentication tokens for all protected routes
• Return appropriate 401 status codes for unauthenticated requests

​

1.3 Input Validation

Tests for SQL injection and XSS attacks failed, but likely due to endpoint connectivity rather than successful exploitation. Recommendation:

• Implement strict input validation for all API parameters
• Use parameterized queries for database operations
• Sanitize all user inputs to prevent injection attacks

​

2. Web Vulnerabilities

​

2.1 Security Headers

The application lacks essential security headers that protect against common web vulnerabilities. Recommendation:

• Implement the following security headers:
  • Content-Security-Policy
  • X-Content-Type-Options
  • X-Frame-Options
  • X-XSS-Protection
  • Strict-Transport-Security
  • Referrer-Policy

​

2.2 CORS Misconfiguration

The application may have overly permissive CORS configuration. Recommendation:

• Restrict CORS to specific origins
• Implement proper preflight handling
• Limit allowed HTTP methods
• Control which headers can be accessed

​

2.3 Information Disclosure

The application may leak sensitive information through error messages or headers. Recommendation:

• Implement custom error pages
• Remove version information from headers
• Sanitize error messages in production
• Configure proper logging levels

​

Remediation Plan

​

Priority 1: Critical Fixes (1-2 days)

1. API Endpoints Implementation
   • Implement proper API route handling for AI endpoints
   • Set up correct middleware chain for authentication
   • Add request validation middleware
2. Security Headers
   • Configure appropriate security headers for all responses
   • Implement a Content Security Policy
   • Add middleware to consistently apply security headers

​

Priority 2: High-Risk Issues (3-5 days)

1. CORS Configuration
   • Implement restrictive CORS policy
   • Configure proper origin validation
   • Test cross-origin requests thoroughly
2. Input Validation
   • Enhance input validation for all API endpoints
   • Implement rate limiting for API requests
   • Add payload size validation

​

Priority 3: Medium-Risk Issues (1-2 weeks)

1. Information Disclosure
   • Review and sanitize error handling
   • Implement custom error pages
   • Configure proper HTTP headers
2. Authentication Hardening
   • Implement token rotation
   • Add additional IP-based verification
   • Implement proper session management

​

Conclusion

The penetration testing has identified several security issues that need to be addressed before deployment. While authentication bypass testing showed robust protection against common attack vectors, the endpoint security and web vulnerability tests revealed areas needing improvement. By following the proposed remediation plan, the application’s security posture can be significantly improved, reducing the risk of exploitation and data breaches.

​

Next Steps

1. Review and prioritize findings
2. Implement critical fixes immediately
3. Re-test after implementing fixes
4. Document security best practices
5. Incorporate security testing into CI/CD pipeline
