Vulnerability Code Signature
Attack Data Flow
| Stage | Detail |
|---|---|
| Source | Authentication endpoint |
| Vector | Flawed logic allows bypassing authentication checks |
| Sink | Access to protected resources |
| Impact | Account takeover, unauthorized access |
Vulnerable Code Pattern
// ❌ VULNERABLE: Improper Authentication
app.post('/login', (req, res) => {
const { username, password } = req.body;
// Taint sink: weak or bypassable validation
if (username === 'admin' || password === 'secret') {
req.session.authenticated = true;
res.send('Logged in');
}
});
Secure Code Pattern
// ✅ SECURE: Robust Authentication
const bcrypt = require('bcrypt');
app.post('/login', async (req, res) => {
const { username, password } = req.body;
const user = await db.getUser(username);
// Sanitized validation: secure password comparison
if (user && await bcrypt.compare(password, user.passwordHash)) {
req.session.authenticated = true;
res.send('Logged in');
} else {
res.status(401).send('Invalid credentials');
}
});
