# Security Implementation Summary
|
|
|
|
## Overview
|
|
This document describes the security measures implemented in the Ospabhost 8.1 platform to protect against common web application vulnerabilities.
|
|
|
|
## Implemented Security Measures
|
|
|
|
### 1. 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
|
|
