security: implement CRITICAL and MEDIUM security fixes with environment profiles
This commit addresses all CRITICAL and MEDIUM security vulnerabilities
identified in the security audit with environment-aware configuration.
## Docker Compose Profiles
- Added docker-compose.dev.yml for development (relaxed security)
- Added docker-compose.prod.yml for production (strict security)
- Environment-specific configurations for rate limiting, CSRF, logging
## CRITICAL Fixes (P0)
1. Fixed insecure random number generation
- Replaced Math.random() with crypto.randomBytes() for verification codes
- Now cryptographically secure
2. Implemented rate limiting
- express-rate-limit for all endpoints
- Strict limits on auth endpoints (5 attempts in dev=off, prod=5)
- Email endpoint limits (20 in dev, 3 in prod)
- API-wide rate limiting
3. Added request body size limits
- Development: 50MB (for testing)
- Production: 10KB (security)
4. Fixed user enumeration vulnerability
- Generic error message for registration
- No disclosure of which field exists
5. Added security headers
- helmet.js with CSP, HSTS, XSS protection
- No-sniff, hide powered-by headers
## MEDIUM Fixes (P1)
6. Strengthened password policy
- Environment-aware validation (8+ chars)
- Production: requires uppercase, lowercase, number
- Development: relaxed for testing
7. Enhanced input validation
- Validation for all auth endpoints
- WSDC ID validation (numeric, max 10 digits)
- Name validation (safe characters only)
- Email normalization
8. Added input sanitization
- DOMPurify for XSS prevention
- Sanitize all user inputs in emails
- Timing-safe string comparison for tokens
9. Improved error handling
- Generic errors in production
- Detailed errors only in development
- Proper error logging
10. Enhanced CORS configuration
- Whitelist-based origin validation
- Environment-specific allowed origins
- Credentials support
## New Files
- backend/src/config/security.js - Environment-aware security config
- backend/src/middleware/rateLimiter.js - Rate limiting middleware
- backend/src/utils/sanitize.js - Input sanitization utilities
- backend/.env.example - Development environment template
- backend/.env.production.example - Production environment template
- docker-compose.dev.yml - Development overrides
- docker-compose.prod.yml - Production configuration
- docs/DEPLOYMENT.md - Complete deployment guide
- docs/SECURITY_AUDIT.md - Full security audit report
- .gitignore - Updated to exclude .env files
## Dependencies Added
- helmet (^8.1.0) - Security headers
- express-rate-limit (^8.2.1) - Rate limiting
- dompurify (^3.3.0) - XSS prevention
- jsdom (^27.2.0) - DOM manipulation for sanitization
## Testing
- ✅ Password validation works (weak passwords rejected)
- ✅ User enumeration fixed (generic error messages)
- ✅ WSDC lookup functional
- ✅ Registration flow working
- ✅ Rate limiting active (environment-aware)
- ✅ Security headers present
## Usage

### Environment Variables
|
||||
|
||||
**Critical Security Variables:**
|
||||
```bash
|
||||
# Must be changed in production!
|
||||
JWT_SECRET=<64-char-random-string>
|
||||
DATABASE_URL=postgresql://user:STRONG_PASSWORD@host:5432/dbname
|
||||
|
||||
# AWS credentials - use IAM roles in production
|
||||
AWS_ACCESS_KEY_ID=<your-key>
|
||||
AWS_SECRET_ACCESS_KEY=<your-secret>
|
||||
```
|
||||
|
||||
**Security Settings:**
|
||||
```bash
|
||||
# Production values
|
||||
RATE_LIMIT_ENABLED=true
|
||||
RATE_LIMIT_AUTH_MAX=5
|
||||
RATE_LIMIT_EMAIL_MAX=3
|
||||
ENABLE_CSRF=true
|
||||
BODY_SIZE_LIMIT=10kb
|
||||
|
||||
# Development values
|
||||
RATE_LIMIT_ENABLED=false
|
||||
RATE_LIMIT_AUTH_MAX=100
|
||||
ENABLE_CSRF=false
|
||||
BODY_SIZE_LIMIT=50mb
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## SSL/HTTPS Configuration
|
||||
|
||||
### Development (HTTP)
|
||||
No SSL required - runs on http://localhost:8080
|
||||
|
||||
### Production (HTTPS)
|
||||
|
||||
1. **Obtain SSL certificates**
|
||||
```bash
|
||||
# Using Let's Encrypt (certbot)
|
||||
certbot certonly --standalone -d spotlight.cam -d www.spotlight.cam
|
||||
```
|
||||
|
||||
2. **Configure nginx**
|
||||
Update `nginx/conf.d/default.conf`:
|
||||
```nginx
|
||||
server {
|
||||
listen 443 ssl http2;
|
||||
server_name spotlight.cam www.spotlight.cam;
|
||||
|
||||
ssl_certificate /etc/nginx/ssl/fullchain.pem;
|
||||
ssl_certificate_key /etc/nginx/ssl/privkey.pem;
|
||||
|
||||
# SSL configuration
|
||||
ssl_protocols TLSv1.2 TLSv1.3;
|
||||
ssl_ciphers HIGH:!aNULL:!MD5;
|
||||
ssl_prefer_server_ciphers on;
|
||||
}
|
||||
|
||||
# Redirect HTTP to HTTPS
|
||||
server {
|
||||
listen 80;
|
||||
server_name spotlight.cam www.spotlight.cam;
|
||||
return 301 https://$server_name$request_uri;
|
||||
}
|
||||
```
|
||||
|
||||
3. **Mount SSL certificates in docker-compose.prod.yml**
|
||||
Already configured to mount `./ssl:/etc/nginx/ssl:ro`
|
||||

|
||||
|
||||
## Database Management
|
||||
|
||||
### Backups
|
||||
|
||||
**Automated backup script:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# scripts/backup-db.sh
|
||||
|
||||
DATE=$(date +%Y%m%d_%H%M%S)
|
||||
BACKUP_DIR="./backups"
|
||||
DB_CONTAINER="spotlightcam-db"
|
||||
|
||||
docker exec $DB_CONTAINER pg_dump -U spotlightcam spotlightcam > "$BACKUP_DIR/backup_$DATE.sql"
|
||||
|
||||
# Keep only last 7 days
|
||||
find $BACKUP_DIR -name "backup_*.sql" -mtime +7 -delete
|
||||
```
|
||||
|
||||
**Setup cron job:**
|
||||
```bash
|
||||
# Daily backup at 2 AM
|
||||
0 2 * * * /path/to/spotlightcam/scripts/backup-db.sh
|
||||
```
|
||||
|
||||
### Restore from backup
|
||||
|
||||
```bash
|
||||
cat backups/backup_YYYYMMDD_HHMMSS.sql | docker exec -i spotlightcam-db psql -U spotlightcam spotlightcam
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Monitoring & Logging
|
||||
|
||||
### View logs
|
||||
|
||||
```bash
|
||||
# All services
|
||||
docker compose logs -f
|
||||
|
||||
# Specific service
|
||||
docker compose logs -f backend
|
||||
docker compose logs -f nginx
|
||||
|
||||
# Last 100 lines
|
||||
docker compose logs --tail 100 backend
|
||||
```
|
||||
|
||||
### Production log management
|
||||
|
||||
Logs are configured with rotation:
|
||||
- Max size: 10MB per file
|
||||
- Max files: 3
|
||||
- Located in Docker's logging directory
|
||||
|
||||
**View logs:**
|
||||
```bash
|
||||
docker compose -f docker-compose.yml -f docker-compose.prod.yml logs --tail 100 -f
|
||||
```

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Backend won't start
|
||||
|
||||
**Check logs:**
|
||||
```bash
|
||||
docker compose logs backend
|
||||
```
|
||||
|
||||
**Common issues:**
|
||||
- Missing environment variables
|
||||
- Database connection failed
|
||||
- Port already in use
|
||||
- Missing npm packages
|
||||
|
||||
### Database connection failed
|
||||
|
||||
**Check database is running:**
|
||||
```bash
|
||||
docker compose ps db
|
||||
```
|
||||
|
||||
**Test connection:**
|
||||
```bash
|
||||
docker compose exec backend npx prisma db push
|
||||
```
|
||||
|
||||
### Emails not sending
|
||||
|
||||
**Check AWS SES configuration:**
|
||||
- Verify AWS credentials are correct
|
||||
- Check SES is in production mode (not sandbox)
|
||||
- Verify sender email is verified in SES
|
||||
- Check CloudWatch logs for SES errors
|
||||
|
||||
### Rate limiting too strict
|
||||
|
||||
**Temporary disable (development only):**
|
||||
```bash
|
||||
# In .env
|
||||
RATE_LIMIT_ENABLED=false
|
||||
```
|
||||
|
||||
**Adjust limits:**
|
||||
```bash
|
||||
# In .env
|
||||
RATE_LIMIT_AUTH_MAX=10 # Allow 10 attempts instead of 5
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Scaling Considerations
|
||||
|
||||
### Horizontal Scaling
|
||||
|
||||
For high traffic, consider:
|
||||
1. Load balancer (nginx, HAProxy)
|
||||
2. Multiple backend containers
|
||||
3. Redis for session/rate limit storage
|
||||
4. Managed database (AWS RDS, DigitalOcean)
|
||||
5. CDN for static assets
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
- Enable gzip compression in nginx
|
||||
- Add Redis for caching
|
||||
- Use connection pooling for database
|
||||
- Implement database read replicas
|
||||
- Use CDN for avatar images
|
||||

|
||||
|
||||
## 🔴 CRITICAL Issues (P0) - FIX IMMEDIATELY
|
||||
|
||||
### 1. Secrets Exposed in `.env` File (CWE-798)
|
||||
|
||||
**Severity:** 🔴 CRITICAL
|
||||
**OWASP:** A02:2021 - Cryptographic Failures
|
||||
**File:** `backend/.env`
|
||||
|
||||
**Issue:**
|
||||
```bash
|
||||
JWT_SECRET=dev-secret-key-12345-change-in-production
|
||||
AWS_ACCESS_KEY_ID=your-aws-access-key-id
|
||||
AWS_SECRET_ACCESS_KEY=your-aws-secret-access-key
|
||||
DATABASE_URL=postgresql://spotlightcam:spotlightcam123@db:5432/spotlightcam
|
||||
```
|
||||
|
||||
**Vulnerabilities:**
|
||||
- Weak JWT secret key
|
||||
- Default placeholder AWS credentials
|
||||
- Database password in plain text
|
||||
- `.env` file may be committed to git
|
||||
|
||||
**Impact:**
|
||||
- Attacker can forge JWT tokens
|
||||
- Potential unauthorized access to AWS services
|
||||
- Database compromise
|
||||
|
||||
**Recommendation:**
|
||||
```bash
|
||||
# Use strong random secrets (at least 32 characters)
|
||||
JWT_SECRET=$(openssl rand -base64 32)
|
||||
|
||||
# Use AWS IAM roles instead of access keys (in production)
|
||||
# Or use AWS Secrets Manager
|
||||
|
||||
# Use environment variables in production (Kubernetes secrets, Docker secrets, etc.)
|
||||
# Never commit .env to git - add to .gitignore
|
||||
```
|
||||
|
||||
**Action:**
|
||||
1. Generate strong JWT secret: `openssl rand -base64 64`
|
||||
2. Use AWS IAM roles or Secrets Manager
|
||||
3. Verify `.env` is in `.gitignore`
|
||||
4. Rotate all secrets immediately if `.env` was committed
|
||||
|
||||

|
||||
|
||||
### 2. Insecure Random Number Generation (CWE-338)
|
||||
|
||||
**Severity:** 🔴 CRITICAL
|
||||
**OWASP:** A02:2021 - Cryptographic Failures
|
||||
**File:** `backend/src/utils/auth.js:38`
|
||||
|
||||
**Issue:**
|
||||
```javascript
|
||||
function generateVerificationCode() {
|
||||
return Math.floor(100000 + Math.random() * 900000).toString();
|
||||
}
|
||||
```
|
||||
|
||||
**Vulnerabilities:**
|
||||
- `Math.random()` is NOT cryptographically secure
|
||||
- Predictable verification codes
|
||||
- Can be brute-forced
|
||||
|
||||
**Impact:**
|
||||
- Attacker can predict verification codes
|
||||
- Account takeover possible
|
||||
|
||||
**Recommendation:**
|
||||
```javascript
|
||||

```javascript
|
||||
body('password')
|
||||
.isLength({ min: 6 }) // Too weak!
|
||||
```
|
||||
|
||||
And in `auth.js:441`:
|
||||

### 21. No Password Strength Meter Feedback
|
||||
|
||||
**Severity:** 🔵 LOW
|
||||
|
||||
**Recommendation:**
|
||||
Implement server-side password strength validation:
|
||||
```bash
|
||||
npm install zxcvbn
|
||||
```
|
||||
|
||||
```javascript
|
||||
const zxcvbn = require('zxcvbn');
|
||||
|
||||
const result = zxcvbn(password);
|
||||
if (result.score < 3) {
|
||||
return res.status(400).json({
|
||||
error: 'Password too weak',
|
||||
suggestions: result.feedback.suggestions,
|
||||
});
|
||||
}
|
||||
```
