StreamFlow Security Implementation - Complete Summary

Overview

Date: December 15, 2025
Version: 2.0
Status: PRODUCTION READY
Compliance: CWE-532 | CWE-778 | CWE-209 | CWE-391


Latest Implementation: CWE-532 (Information Exposure Through Log Files)

What Was Implemented

1. Data Sanitization Utility NEW

File: backend/utils/dataSanitizer.js (153 lines)

Comprehensive utility preventing sensitive data exposure in logs:

  • 8 Functions: sanitizeForLogging, sanitizeUserForExport, maskToken, maskEmail, etc.
  • 35+ Sensitive Fields: Automatically detects and redacts passwords, tokens, secrets, PII
  • Recursive Sanitization: Handles nested objects and arrays
  • Export Safety: Removes password hashes from user data exports

Usage Example:

const { sanitizeRequestBody } = require('./utils/dataSanitizer');
console.log('Request:', sanitizeRequestBody(req.body));
// Output: { username: 'john', password: '[REDACTED]' }

2. Critical Logging Violations Fixed (5 Issues)

🔴 CRITICAL: Default Admin Password Logged

File: backend/database/db.js

Before:

console.log('✓ Default admin user created (username: admin, password: admin)');

After:

console.log('✓ Default admin user created (username: admin)');
console.log('⚠ SECURITY: Change the default admin password immediately!');

🟠 HIGH: VPN Config Request Body Logged

File: backend/routes/vpn-configs.js

Before:

console.log('[VPN-CONFIG] Body:', req.body); // Contains VPN credentials!

After:

// CWE-532: Do not log request body - may contain sensitive VPN credentials

🟠 HIGH: JWT Token Details Logged

File: backend/middleware/auth.js

Before:

logger.info(`[AUTH] Verifying token, JWT_SECRET length: ${JWT_SECRET.length}`);

After:

// CWE-532: Do not log tokens or token details - they are credentials
logger.info('[AUTH] Verifying authentication token');

🟡 MEDIUM: Password Hashes in Backup Exports

File: backend/routes/backup.js

Before:

const userData = await dbAll('SELECT * FROM users WHERE id = ?', [userId]);
// Includes password, two_factor_secret, backup_codes

After:

const userData = await dbAll(
  `SELECT id, username, email, role, two_factor_enabled, is_active, 
          created_at, updated_at, last_login_at, last_login_ip, 
          password_changed_at, password_expires_at 
   FROM users WHERE id = ?`, 
  [userId]
);
// CWE-532: Excludes password, two_factor_secret, backup_codes

🟢 LOW: VPN Config ID Exposure

File: backend/routes/vpn-configs.js (3 locations)

Before:

console.log(`[VPN-CONFIG] Config ${req.params.id} marked as active`);

After:

console.log(`[VPN-CONFIG] Configuration marked as active for user ${req.user.userId}`);

Quick Reference

CWE-532 Compliance

// ✅ GOOD: Sanitize before logging
const { sanitizeRequestBody } = require('./utils/dataSanitizer');
console.log('Request:', sanitizeRequestBody(req.body));

// ❌ BAD: Never log raw request body
console.log('Request:', req.body); // Contains passwords!

CWE-778 Compliance

// ✅ GOOD: Log admin activities
await SecurityAuditLogger.logAdminActivity(adminId, 'user_created', {
  targetUserId, targetUsername, adminUsername, changes
});

// ✅ GOOD: Log sensitive data access
await SecurityAuditLogger.logSensitiveDataAccess(userId, 'user_list', {
  recordCount, scope: 'all', accessMethod: 'view'
});
