# Authentication & Authorization Flaws Analysis
|
|
|
|
## Already Fixed ✅
|
|
|
|
1. **Missing Token Type Validation** ✅
|
|
- Fixed in `auth-enhanced.js` line 31
|
|
- Checks `decoded.type !== 'admin'`
|
|
- Prevents gallery tokens from accessing admin endpoints
|
|
|
|
2. **No Audit Logging** ✅
|
|
- Added `login_attempts` table
|
|
- Tracks all login attempts with IP, user agent, timestamp
|
|
- Automatic cleanup of old records
|
|
|
|
3. **Account Lockout Protection** ✅
|
|
- Lockout after 5 failed attempts
|
|
- 30-minute lockout duration
|
|
- Prevents brute force attacks
|
|
|
|
4. **Basic Session Management** ✅
|
|
- Added session timeout middleware
|
|
- Tracks active sessions
|
|
- Can invalidate sessions
|
|
|
|
## Still Needs Fixing ❌
|
|
|
|
### 1. Weak Password Requirements 🔴
|
|
- **Current**: No minimum length validation
|
|
- **Required**: Minimum 12 characters + complexity
|
|
- **Risk**: Vulnerable to brute force
|
|
|
|
### 2. Rate Limiting Bypass 🔴
|
|
- **Current**: Invalid JWT bypasses rate limiting
|
|
- **Location**: `server.js:64-71`
|
|
- **Risk**: Attackers can spam with invalid tokens
|
|
|
|
### 3. No Password Complexity 🟡
|
|
- **Current**: Any 6+ character password accepted
|
|
- **Required**: Upper, lower, number, special char
|
|
- **Risk**: Weak passwords
|
|
|
|
### 4. No Token Revocation 🟡
|
|
- **Current**: Tokens valid until expiration
|
|
- **Required**: Blacklist/revocation mechanism
|
|
- **Risk**: Can't invalidate compromised tokens
|
|
|
|
### 5. Fixed Bcrypt Rounds 🟡
|
|
- **Current**: Hardcoded to 10 rounds
|
|
- **Required**: Configurable (12-14 recommended)
|
|
- **Risk**: May become insufficient over time
|
|
|
|
### 6. In-Memory Session Storage 🟡
|
|
- **Current**: Sessions stored in memory
|
|
- **Required**: Redis or database storage
|
|
- **Risk**: Lost on restart, not scalable
|
|
|
|
## Priority Fixes
|
|
|
|
1. **Rate Limiting Bypass** (Critical)
|
|
2. **Password Requirements** (High)
|
|
3. **Password Complexity** (High)
|
|
4. **Token Revocation** (Medium)
|
|
5. **Bcrypt Rounds** (Medium)
|
|
6. **Session Storage** (Low - for scalability) |
