LiteMIDgo Security Audit Report

🔴 CRITICAL SECURITY ISSUES

1. EXPOSED CREDENTIALS IN .env FILE

  • Risk: HIGH - Real ServiceNow credentials are hardcoded in .env
  • Location: /Users/surendraraika/projects/servicenowUtils/liteMIDgo/.env
  • Details: Contains actual username, password, and instance URL
  • Impact: Unauthorized access to ServiceNow instance

2. NO AUTHENTICATION ON SERVER ENDPOINTS

  • Risk: HIGH - Server endpoints are completely open
  • Location: internal/server/server.go
  • Details: No authentication middleware, CORS protection, or API keys
  • Impact: Anyone can send data to ServiceNow through the proxy

🟡 MEDIUM SECURITY ISSUES

3. INSUFFICIENT INPUT VALIDATION

  • Risk: MEDIUM - Limited validation of incoming JSON payloads
  • Location: internal/server/server.go:116-124
  • Details: Only checks for valid JSON, no payload size limits or content validation
  • Impact: Potential DoS attacks, malformed data injection

4. DEBUG INFORMATION LEAKAGE

  • Risk: MEDIUM - Debug mode exposes sensitive information
  • Location: agent/main.go:129-136, cmd/root.go:54-55
  • Details: Debug mode prints full JSON payloads and configuration paths
  • Impact: Information disclosure in logs

5. NO RATE LIMITING

  • Risk: MEDIUM - No rate limiting on API endpoints
  • Location: All server endpoints
  • Details: Unlimited requests can be made to /proxy/ecc_queue
  • Impact: DoS attacks, ServiceNow API quota exhaustion

6. PLAIN HTTP COMMUNICATION

  • Risk: MEDIUM - Agent-server communication uses HTTP by default
  • Location: Agent configuration
  • Details: No TLS encryption for internal communication
  • Impact: Man-in-the-middle attacks, credential interception

🟢 LOW SECURITY ISSUES

7. ERROR INFORMATION DISCLOSURE

  • Risk: LOW - Detailed error messages in responses
  • Location: internal/server/server.go:118-120
  • Details: Error messages include internal error details
  • Impact: Information disclosure about system internals

8. NO SECURITY HEADERS

  • Risk: LOW - Missing security HTTP headers
  • Location: Server responses
  • Details: No CSP, HSTS, X-Frame-Options headers
  • Impact: Client-side attack vectors

📋 SECURITY RECOMMENDATIONS

Immediate Actions Required:

  1. REMOVE REAL CREDENTIALS from .env file
  2. IMPLEMENT AUTHENTICATION on server endpoints
  3. ADD RATE LIMITING to prevent abuse
  4. ENABLE HTTPS for all communications

Recommended Improvements:

  1. Add API key or JWT authentication
  2. Implement request size limits
  3. Add CORS configuration
  4. Enable TLS for agent-server communication
  5. Add comprehensive input validation
  6. Implement audit logging
  7. Add security headers
  8. Remove debug information from production builds

Configuration Security:

  1. Use environment-specific configurations
  2. Implement secrets management
  3. Add configuration validation
  4. Use secure defaults

🛡️ SECURITY BEST PRACTICES TO IMPLEMENT

  1. Authentication & Authorization

    • API key authentication
    • JWT tokens for session management
    • Role-based access control

  2. Transport Security

    • TLS 1.2+ for all communications
    • Certificate validation
    • Secure cipher suites

  3. Input Validation

    • JSON schema validation
    • Payload size limits
    • Content type validation

  4. Rate Limiting & DoS Protection

    • Request rate limiting per IP
    • Payload size limits
    • Connection limits

  5. Logging & Monitoring

    • Security event logging
    • Failed authentication tracking
    • Anomaly detection

  6. Configuration Security

    • Secrets management integration
    • Environment-specific configs
    • Secure default settings
