Weak Password Policies in Laravel: Risks & Fixes

 

Weak Password Policies in Laravel: A Security Concern

Laravel, a popular PHP framework, simplifies web application development but can be vulnerable if weak password policies are implemented. Password policies are the backbone of authentication security, and inadequate policies can expose your application to brute-force attacks, credential stuffing, and unauthorized access.

In this blog, we’ll explore weak password policies in Laravel, the risks they pose, and how to fix them with practical coding examples. We’ll also demonstrate how our free Website Security Scanner tool can help identify such vulnerabilities.

Why Weak Password Policies Matter

Weak password policies allow users to set easy-to-guess passwords like "123456" or "password," making it easier for attackers to breach your system. Here's what typically constitutes weak policies:

• No minimum password length
• Lack of complexity (e.g., no requirement for special characters or numbers)
• No password history enforcement (allowing password reuse)
• Lack of rate-limiting for login attempts

Example: Implementing Strong Password Policies in Laravel

By default, Laravel uses the Hash::make method for password hashing, but enforcing strong password rules requires additional validation. Let’s improve password strength:

Basic Password Validation in Laravel

$request->validate([
    'password' => [
        'required',
        'string',
        'min:8', // Minimum 8 characters
        'regex:/[a-z]/', // At least one lowercase letter
        'regex:/[A-Z]/', // At least one uppercase letter
        'regex:/[0-9]/', // At least one number
        'regex:/[@$!%*?&]/', // At least one special character
    ],
]);

This ensures users create strong passwords meeting the specified criteria.

Advanced: Adding Rate-Limiting

Prevent brute-force attacks by adding rate-limiting to your login functionality:

use Illuminate\Support\Facades\RateLimiter;

RateLimiter::for('login', function (Request $request) {
    return Limit::perMinute(5)->by($request->input('email'));
});

If users exceed five login attempts per minute, they’ll be temporarily blocked, making it harder for attackers to guess credentials.

Case Study: Analyzing Weak Password Policies

Here’s an example report from our tool highlighting weak password policies in a sample Laravel application. It identifies issues such as:

1. No enforcement of special character usage
2. Passwords shorter than eight characters allowed
3. Reused passwords enabled

An example of a vulnerability assessment report generated with our free tool provides insights into possible vulnerabilities.

Enhancing Security with Password History

To prevent users from reusing old passwords, implement a password history table:

Migration for Password History

php artisan make:migration create_password_histories_table

Update the migration file:

Schema::create('password_histories', function (Blueprint $table) {
    $table->id();
    $table->unsignedBigInteger('user_id');
    $table->string('password');
    $table->timestamps();
});

Storing Old Passwords

Update the user registration or password update logic:

use Illuminate\Support\Facades\Hash;

if (Hash::check($request->password, $user->password)) {
    return back()->withErrors(['password' => 'You cannot reuse an old password.']);
}

// Save the new password
$user->password = Hash::make($request->password);
$user->save();

Conclusion

Weak password policies leave your Laravel applications vulnerable to attacks. By implementing strong password validation, rate-limiting, and password history enforcement, you can significantly enhance your app’s security.
