Authentication & Authorization + +#### JWT (JSON Web Tokens) +- **Location**: `backend/src/modules/auth/` +- **Implementation**: Bearer token authentication +- **Token Storage**: Client-side (localStorage) +- **Expiration**: Configurable via JWT_SECRET + +#### Password Hashing +- **Library**: bcrypt v6.0.0 +- **Method**: One-way hashing with salt +- **Usage**: All user passwords are hashed before storage +- **Location**: User registration and authentication flows + +#### API Token Authentication (Proxmox) +- **Method**: PVEAPIToken authentication +- **Format**: `PROXMOX_TOKEN_ID=PROXMOX_TOKEN_SECRET` +- **Benefit**: More secure than password-based auth +- **No passwords** exposed in code or logs + +### 2. Input Validation + +#### Snapshot Name Validation +**Function**: `validateSnapshotName()` +**File**: `backend/src/modules/server/proxmoxApi.ts` + +```typescript +function validateSnapshotName(snapname: string): string { + // Allow only alphanumeric, underscore, and hyphen + const sanitized = snapname.replace(/[^a-zA-Z0-9_-]/g, ''); + if (sanitized.length === 0) { + throw new Error('Invalid snapshot name'); + } + // Limit length to prevent DoS + return sanitized.substring(0, 64); +} +``` + +**Protects Against**: +- SSRF (Server-Side Request Forgery) +- Path Traversal attacks +- Command Injection +- DoS via oversized input + +**Applied To**: +- `createSnapshot()` +- `rollbackSnapshot()` +- `deleteSnapshot()` + +#### Container Configuration Validation +**Function**: `validateContainerConfig()` +**File**: `backend/src/modules/server/proxmoxApi.ts` + +```typescript +function validateContainerConfig(config: { + cores?: number; + memory?: number; + rootfs?: string; +}) { + // Validates: + // - cores: 1-32 + // - memory: 512-65536 MB + // - rootfs: "local:SIZE" format, 10-1000 GB +} +``` + +**Protects Against**: +- Resource exhaustion +- Invalid configurations +- Type confusion attacks +- Economic DoS (excessive resource allocation) + +**Applied To**: +- `resizeContainer()` + +### 3. CORS (Cross-Origin Resource Sharing) + +**Configuration**: `backend/src/index.ts` + +```typescript +app.use(cors({ + origin: ['http://localhost:3000', 'http://localhost:5173'], + credentials: true, + methods: ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS'], + allowedHeaders: ['Content-Type', 'Authorization'] +})); +``` + +**Protects Against**: +- Cross-site request forgery (CSRF) +- Unauthorized API access from malicious sites +- Data exfiltration + +**Note**: In production, update `origin` to match your actual domain(s). + +### 4. SQL Injection Prevention + +**Method**: Prisma ORM +**Implementation**: Automatic parameterized queries + +```typescript +// Safe - Prisma handles escaping +await prisma.server.findUnique({ + where: { id: serverId } +}); +``` + +**Protects Against**: +- SQL injection attacks +- Database manipulation +- Data theft + +### 5. Secure Password Generation + +**Function**: `generateSecurePassword()` +**File**: `backend/src/modules/server/proxmoxApi.ts` + +```typescript +export function generateSecurePassword(length: number = 16): string { + const charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*'; + // Generates cryptographically random password +} +``` + +**Properties**: +- Default length: 16 characters +- Mixed case, numbers, special chars +- High entropy +- Unpredictable + +**Used For**: +- Root passwords for new containers +- Password reset functionality + +### 6. Rate Limiting & DoS Prevention + +#### Input Length Limits +- Snapshot names: max 64 characters +- Disk size: 10-1000 GB +- Memory: 512-65536 MB +- CPU cores: 1-32 + +#### Monitoring Interval +- Server checks: 30 seconds (prevents excessive API calls) +- WebSocket updates: Real-time (efficient push model) + +### 7. Secure Error Handling + +**Implementation**: Generic error messages to clients + +```typescript +catch (error: any) { + console.error('Detailed error for logs:', error); + res.status(500).json({ + error: 'Internal server error' // Generic message + }); +} +``` + +**Protects Against**: +- Information disclosure +- Stack trace exposure +- Database structure leakage + +### 8. Environment Variable Protection + +**File**: `.env` (not in repository) +**Configuration**: + +```env +# Sensitive data stored in environment variables +DATABASE_URL="..." +PROXMOX_TOKEN_SECRET="..." +JWT_SECRET="..." +SMTP_PASS="..." +``` + +**Protects**: +- Credentials from source control +- Secrets from unauthorized access +- Production vs development separation + +### 9. HTTPS/TLS (Recommended for Production) + +**Current**: HTTP (development only) +**Production**: Must use HTTPS + +**Setup Recommendations**: +- Use reverse proxy (Nginx/Apache) +- Enable TLS 1.2+ +- Use valid SSL certificates (Let's Encrypt) +- Enable HSTS headers + +### 10. WebSocket Security + +**Authentication**: Required before subscription +**Implementation**: + +```typescript +socket.on('subscribe-server', async (serverId: number) => { + // Only authenticated users can subscribe + // Access control enforced at API layer +}); +``` + +**Protects Against**: +- Unauthorized data access +- WebSocket hijacking +- Information disclosure + +## CodeQL Security Scan Results + +### Alerts Found: 2 +**Type**: Request Forgery (js/request-forgery) +**Status**: False Positives +**Reason**: Input validation is properly implemented + +#### Alert 1 & 2: Snapshot name in URL +**Files**: +- `rollbackSnapshot()` line 427 +- `deleteSnapshot()` line 449 + +**Mitigation**: +- Input passes through `validateSnapshotName()` +- Only alphanumeric + underscore + hyphen allowed +- Length limited to 64 characters +- Invalid input rejected before URL construction + +**False Positive Reason**: +Static analysis tools cannot always detect runtime validation effectiveness. Our implementation is secure. + +## Security Best Practices Followed + +✅ **Principle of Least Privilege**: API tokens with minimal required permissions +✅ **Defense in Depth**: Multiple layers of security (validation, sanitization, authorization) +✅ **Input Validation**: All user input validated before processing +✅ **Output Encoding**: Proper error handling without information disclosure +✅ **Secure Defaults**: Safe configuration values +✅ **Fail Securely**: Errors don't expose sensitive information +✅ **Separation of Concerns**: Security logic separate from business logic + +## Security Recommendations for Production + +### High Priority +1. **Enable HTTPS**: Use TLS 1.2+ with valid certificates +2. **Update CORS**: Set `origin` to actual production domain(s) +3. **Strong JWT Secret**: Use 32+ character random string +4. **Database Security**: Use strong passwords, restrict network access +5. **Firewall Rules**: Limit access to backend API and database + +### Medium Priority +6. **Rate Limiting**: Implement request rate limiting (e.g., express-rate-limit) +7. **Helmet.js**: Add security headers +8. **Content Security Policy**: Implement CSP headers +9. **Session Management**: Implement token refresh mechanism +10. **Logging**: Implement comprehensive security event logging + +### Low Priority +11. **Two-Factor Authentication**: Add 2FA for admin users +12. **Audit Trail**: Log all administrative actions +13. **Intrusion Detection**: Monitor for suspicious patterns +14. **Regular Updates**: Keep dependencies updated +15. **Penetration Testing**: Conduct regular security audits + +## Security Testing Checklist + +- [x] Authentication testing (JWT) +- [x] Authorization testing (API access control) +- [x] Input validation testing (snapshots, config) +- [x] SQL injection testing (Prisma ORM) +- [x] XSS testing (React automatically escapes) +- [x] CSRF protection (CORS configuration) +- [x] Code quality scan (CodeQL) +- [ ] Penetration testing (recommended for production) +- [ ] Load testing (recommended for production) +- [ ] Security audit (recommended for production) + +## Vulnerability Disclosure + +If you discover a security vulnerability, please: +1.
