Laravel Broken Authentication: How to Detect and Fix It

Broken authentication is a critical security vulnerability that exposes web applications to unauthorized access. For Laravel developers, ensuring robust authentication mechanisms is vital to safeguard user data and maintain trust.

In this post, we’ll explore:

• What is broken authentication?

• How it impacts Laravel applications.

• How to detect it using our free Website Security Scanner.

• A coding example to mitigate it.

What is Broken Authentication?

Broken authentication occurs when a web application's authentication process can be bypassed or exploited due to flaws such as:

• Weak password policies.

• Exposed session IDs.

• Poor implementation of multi-factor authentication (MFA).

In Laravel applications, the misconfiguration of authentication routes or weak password hashing can be the primary culprits.

Impacts of Broken Authentication

Failing to address broken authentication can lead to:

• Unauthorized access to sensitive data.

• Privilege escalation attacks.

• Compromised user accounts.

Let’s delve into how to detect these vulnerabilities and fix them.

Coding Example: Mitigating Broken Authentication in Laravel

Below is an example of how to enforce stricter authentication practices in Laravel using bcrypt for hashing passwords and implementing session management.

Secure Password Hashing

Ensure passwords are hashed securely using Laravel’s bcrypt:

use Illuminate\Support\Facades\Hash;  

// Storing hashed password  
$user->password = Hash::make('your_password');  
$user->save();  

// Verifying password during login  
if (Hash::check('your_password', $user->password)) {  
    // Login successful  
} else {  
    // Authentication failed  
}

Enforcing Multi-Factor Authentication (MFA)

Add MFA to strengthen authentication:

// Example using Laravel package for OTP (One Time Password)  
use OTPAuth;  

$otp = new OTPAuth\TOTP('Label', 'SecretKey');  
echo 'Your OTP is: ' . $otp->now();

Session Management

To prevent session hijacking, secure your sessions in the config/session.php:

'secure' => env('SESSION_SECURE_COOKIE', true),  
'http_only' => true,  
'same_site' => 'strict',
