|
||||
|
||||
## Executive Summary
|
||||
|
||||
I've completed a comprehensive security audit of your CRM server project. The project has **good security foundations** with several protective measures in place, but there are **2 critical dependency vulnerabilities** and several **medium-priority security improvements** needed.
|
||||
|
||||
---
|
||||
|
||||
## ✅ STRENGTHS
|
||||
|
||||
### 1. **Authentication & Authorization**
|
||||
- ✅ JWT tokens stored in httpOnly cookies (XSS protection)
|
||||
- ✅ SameSite=Strict cookies (CSRF protection)
|
||||
- ✅ Bcrypt password hashing (12 rounds)
|
||||
- ✅ Separate access & refresh tokens
|
||||
- ✅ Role-based access control (admin/member)
|
||||
- ✅ Temporary password system for onboarding
|
||||
|
||||
### 2. **Input Validation & Sanitization**
|
||||
- ✅ Zod schemas for request validation
|
||||
- ✅ XSS protection via xss-clean middleware
|
||||
- ✅ Custom malicious pattern detection in `validateBody.js`
|
||||
- ✅ SQL injection protection via Drizzle ORM (parameterized queries)
|
||||
|
||||
### 3. **Rate Limiting**
|
||||
- ✅ Login rate limiter (5 attempts/15min)
|
||||
- ✅ API rate limiter (100 req/15min production, 1000 dev)
|
||||
- ✅ Sensitive operations limiter (3 attempts/15min)
|
||||
|
||||
### 4. **Security Headers & CORS**
|
||||
- ✅ Helmet middleware with CSP and HSTS
|
||||
- ✅ Configured CORS with credentials support
|
||||
- ✅ Body size limits (10MB)
|
||||
|
||||
### 5. **Data Encryption**
|
||||
- ✅ AES-256-GCM for email passwords

|
||||
|
||||
## 🚨 CRITICAL VULNERABILITIES
|
||||
|
||||
### 1. **NPM Dependencies - 2 Low Severity Issues** ⚠️
|
||||
|
||||
**better-auth v1.3.34** (2 vulnerabilities):
|
||||
- **GHSA-wmjr-v86c-m9jj**: Multi-session sign-out hook allows forged cookies to revoke arbitrary sessions (CVSS 9.6)
|
||||
- Severity: Low (but high CVSS score)
|
||||
- Fix available: v1.4.4
|
||||
|
||||
- **GHSA-569q-mpph-wgww**: External request basePath modification DoS
|
||||
- Severity: Low
|
||||
- Fix available: v1.4.4
|
||||
|
||||
**express v4.21.2**:
|
||||
- **GHSA-pj86-cfqh-vqx6**: Improper control of query properties modification
|
||||
- Severity: Low
|
||||
- Fix available: v4.22.0
|
||||
|
||||
**Fix Available**: Yes
|
||||
|
||||
**Recommended Action**:
|
||||
```bash
|
||||
npm audit fix
|
||||
# This will update:
|
||||
# - better-auth: 1.3.34 → 1.4.4
|
||||
# - express: 4.21.2 → 4.22.1
|
||||
```
|
||||
|
||||
**Additional Outdated Packages**:
|
||||
- `dotenv`: 16.6.1 → 17.2.3 (latest)
|
||||
- `zod`: 4.1.12 → 4.1.13
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ HIGH PRIORITY ISSUES
|
||||
|
||||
### 2. **Environment File Security** 🔴
|
||||
|
||||
**Issue**: `.env` file contains default/weak secrets
|
||||
|
||||
**Findings**:
|
||||
- ✅ `.env` is properly gitignored
|
||||
- ✅ Never committed to git history
|
||||
- ❌ Contains default/weak secrets that should be changed in production
|
||||
|
||||
**Secrets Found**:
|
||||
```env
|
||||
JWT_SECRET=your-super-secret-jwt-key-change-this-in-production
|
||||
JWT_REFRESH_SECRET=your-super-secret-refresh-key-change-this-in-production
|
||||
BETTER_AUTH_SECRET=your-super-secret-better-auth-key-change-this-in-production
|
||||
```
|
||||
|
||||
**Recommendation**:
|
||||
```bash
|
||||
# Generate strong secrets:
|
||||
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
|
||||
|
||||
# For each secret in .env:
|
||||
JWT_SECRET=<generated-random-hex>
|
||||
JWT_REFRESH_SECRET=<generated-random-hex>
|
||||
BETTER_AUTH_SECRET=<generated-random-hex>
|
||||
```
|
||||
|
||||
**Best Practices**:
|
||||
- Generate strong, random secrets for production
|
||||
- Consider using secret management (HashiCorp Vault, AWS Secrets Manager)
|
||||
- Rotate secrets regularly (every 90 days)
|
||||
- Never commit secrets to version control
|
||||
|
||||
### 3. **Database Credentials in docker-compose.yml** 🟡
|
||||
|
||||
**Issue**: Hardcoded database password in docker-compose.yml
|
||||
|
||||
**Current Code**:
|
||||
```yaml
|
||||
environment:
|
||||
POSTGRES_PASSWORD: heslo123
|
||||
POSTGRES_DB: crm
|
||||
POSTGRES_USER: admin
|
||||
```
|
||||
|
||||
**Recommendation**:
|
||||
```yaml
|
||||
environment:
|
||||
POSTGRES_PASSWORD: ${DB_PASSWORD}
|
||||
POSTGRES_DB: ${DB_NAME}
|
||||
POSTGRES_USER: ${DB_USER}
|
||||
```
|
||||
|
||||
### 4. **Password Encryption Salt** 🟡
|
||||
|
||||
**Location**: `src/utils/password.js:75`
|
||||
|
||||
**Issue**: Hardcoded salt value 'salt' - should be unique per encryption
|
||||
|
||||
**Current Code**:
|
||||
```javascript
|
||||
const key = crypto.scryptSync(process.env.JWT_SECRET, 'salt', 32);
|
||||
```
|
||||
|
||||
**Problem**: Using a static salt means all encrypted passwords use the same key derivation, reducing security.
|
||||
|
||||
**Recommendation**:
|
||||
```javascript
|
||||
// Generate random salt per encryption
|
||||
const salt = crypto.randomBytes(16);
|
||||
const key = crypto.scryptSync(process.env.JWT_SECRET, salt, 32);
|
||||
// Store: `${salt.toString('hex')}:${iv.toString('hex')}:${authTag.toString('hex')}:${encrypted}`
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🟡 MEDIUM PRIORITY IMPROVEMENTS
|
||||
|
||||
### 5. **Session Security**
|
||||
|
||||
**Current Issues**:
|
||||
- ❌ No session invalidation on password change
|
||||
- ❌ No maximum concurrent sessions per user
|
||||
- ❌ No session timeout warnings
|
||||
- ❌ Refresh tokens not stored in database (cannot revoke)
|
||||
|
||||
**Recommendation**:
|
||||
```javascript
|
||||
// Add session tracking table
|
||||
export const sessions = pgTable('sessions', {
|
||||
id: uuid('id').primaryKey().defaultRandom(),
|
||||
userId: uuid('user_id').references(() => users.id, { onDelete: 'cascade' }),
|
||||
refreshToken: text('refresh_token').notNull(),
|
||||
ipAddress: text('ip_address'),
|
||||
userAgent: text('user_agent'),
|
||||
expiresAt: timestamp('expires_at').notNull(),
|
||||
createdAt: timestamp('created_at').defaultNow()
|
||||
});
|
||||
|
||||
// Invalidate all sessions on password change
|
||||
// Limit to 5 concurrent sessions per user
|
||||
```
|
||||
|
||||
### 6. **Password Policy Enhancement**
|
||||
|
||||
**Current Policy** (from code review):
|
||||
- ✅ Minimum 8 characters
|
||||
- ✅ Must contain uppercase, lowercase, number, symbol
|
||||
|
||||
**Enhancements Needed**:
|
||||
```javascript
|
||||
// Add to password validation:
|
||||
- Minimum 12 characters (currently 8)
|
||||
- Check against common password list (e.g., have-i-been-pwned)
|
||||
- Prevent password reuse (store hash of last 5 passwords)
|
||||
- Add password strength meter on frontend
|
||||
- Enforce password expiration (90 days for admin accounts)
|
||||
```
|
||||
|
||||
### 7. **File Storage Security**
|
||||
|
||||
**Current Issues**:
|
||||
- ❌ Uploaded files stored locally without encryption at rest
|
||||
- ❌ No virus scanning on uploads
|
||||
- ❌ File paths somewhat predictable: `uploads/timesheets/{userId}/{year}/{month}/{filename}`
|
||||
|
||||
**Recommendations**:
|
||||
```bash
|
||||
# 1. Add virus scanning
|
||||
npm install clamscan
|
||||
|
||||
# 2. Encrypt files at rest
|
||||
# Use node's crypto to encrypt files before saving
|
||||
|
||||
# 3. Use UUIDs in paths
|
||||
uploads/timesheets/{uuid}/{uuid}.encrypted
|
||||
```
|
||||
|
||||
**Alternative**: Migrate to cloud storage (AWS S3, Azure Blob) with server-side encryption
|
||||
|
||||
### 8. **Logging Concerns**
|
||||
|
||||
**Issues**:
|
||||
- ❌ No check for sensitive data in logs
|
||||
- ⚠️ Morgan logs all requests (could expose sensitive query params)
|
||||
- ❌ Console.log statements in code (should use winston logger)
|
||||
|
||||
**Recommendation**:
|
||||
```javascript
|
||||
// Configure morgan to skip sensitive routes
|
||||
app.use(morgan('dev', {
|
||||
skip: (req) => {
|
||||
const sensitivePatterns = [
|
||||
/password/i,
|
||||
/token/i,
|
||||
/secret/i,
|
||||
/api\/auth\/login/,
|
||||
/api\/auth\/set-password/
|
||||
];
|
||||
return sensitivePatterns.some(pattern =>
|
||||
pattern.test(req.url) || pattern.test(JSON.stringify(req.body))
|
||||
);
|
||||
}
|
||||
}));
|
||||
|
||||
// Replace all console.log with winston logger
|
||||
import { logger } from './utils/logger.js';
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔵 LOW PRIORITY / BEST PRACTICES
|
||||
|
||||
### 9. **Security Headers Enhancement**
|
||||
|
||||
**Current CSP** is basic. Enhance with:
|
||||
|
||||
```javascript
|
||||
app.use(helmet({
|
||||
contentSecurityPolicy: {
|
||||
directives: {
|
||||
defaultSrc: ["'self'"],
|
||||
scriptSrc: ["'self'"],
|
||||
styleSrc: ["'self'", "'unsafe-inline'"],
|
||||
imgSrc: ["'self'", "data:", "https:"],
|
||||
connectSrc: ["'self'"],
|
||||
fontSrc: ["'self'"],
|
||||
objectSrc: ["'none'"],
|
||||
mediaSrc: ["'none'"],
|
||||
frameSrc: ["'none'"],
|
||||
upgradeInsecureRequests: [],
|
||||
},
|
||||
},
|
||||
hsts: {
|
||||
maxAge: 31536000,
|
||||
includeSubDomains: true,
|
||||
preload: true,
|
||||
},
|
||||
referrerPolicy: { policy: "strict-origin-when-cross-origin" },
|
||||
noSniff: true,
|
||||
xssFilter: true,
|
||||
hidePoweredBy: true
|
||||
}));
|
||||
```
|
||||
|
||||
### 10. **CORS Hardening**
|
||||
|
||||
**Current**:
|
||||
```javascript
|
||||
const corsOptions = {
|
||||
origin: process.env.CORS_ORIGIN || 'http://localhost:5173',
|
||||
credentials: true,
|
||||
optionsSuccessStatus: 200,
|
||||
};
|
||||
```
|
||||
|
||||
**Enhanced**:
|
||||
```javascript
|
||||
const corsOptions = {
|
||||
origin: process.env.CORS_ORIGIN || 'http://localhost:5173',
|
||||
credentials: true,
|
||||
methods: ['GET', 'POST', 'PATCH', 'DELETE'],
|
||||
allowedHeaders: ['Content-Type', 'Authorization'],
|
||||
exposedHeaders: ['Content-Range', 'X-Content-Range'],
|
||||
maxAge: 86400, // 24 hours
|
||||
optionsSuccessStatus: 200
|
||||
};
|
||||
```
|
||||
|
||||
### 11. **Rate Limiting - IP Spoofing Protection**
|
||||
|
||||
Add trust proxy setting:
|
||||
```javascript
|
||||
// In app.js, before rate limiters
|
||||
app.set('trust proxy', 1); // Trust first proxy (nginx, cloudflare, etc.)
|
||||
```
|
||||
|
||||
### 12. **Audit Log Retention**
|
||||
|
||||
**Current Issues**:
|
||||
- ❌ No automatic cleanup of old audit logs
|
||||
- ❌ No log rotation policy
|
||||
- ❌ Unlimited log growth
|
||||
|
||||
**Recommendation**:
|
||||
```javascript
|
||||
// Add cron job to clean old logs
|
||||
import cron from 'node-cron';
|
||||
|
||||
// Run daily at 2 AM
|
||||
cron.schedule('0 2 * * *', async () => {
|
||||
const retentionDays = 90;
|
||||
await db.delete(auditLogs)
|
||||
.where(
|
||||
sql`created_at < NOW() - INTERVAL '${retentionDays} days'`
|
||||
);
|
||||
});
|
||||
```
|
||||
|
||||
### 13. **Additional Security Measures**
|
||||
|
||||
**API Security**:
|
||||
```javascript
|
||||
// Add request ID tracking
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
app.use((req, res, next) => {
|
||||
req.id = uuidv4();
|
||||
res.setHeader('X-Request-ID', req.id);
|
||||
next();
|
||||
});
|
||||
|
||||
// Add timeout middleware
|
||||
import timeout from 'connect-timeout';
|
||||
app.use(timeout('30s'));
|
||||
```
|
||||
|
||||
**Brute Force Protection**:
|
||||
```javascript
|
||||
// Add progressive delays after failed login attempts
|
||||
// Implement account lockout after 10 failed attempts
|
||||
// Add CAPTCHA after 3 failed attempts
|
||||
```
