🔒 Top 10 Fixes for Weak SSL/TLS Configuration in Laravel

Introduction

Laravel is one of the most popular PHP frameworks, widely used for web application development. However, a weak SSL TLS configuration in Laravel can expose even well-coded applications to severe security risks, including man-in-the-middle (MITM) attacks, data breaches, and downgrade exploits.

This blog will walk you through the top 10 ways to fix weak SSL/TLS configuration in Laravel, complete with real-world code examples, screenshots, and a bonus section on our new Web App Penetration Testing Service.

🛡️ What is a Weak SSL/TLS Configuration?

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that secure communication over the internet. When improperly configured in Laravel, attackers can exploit:

• Deprecated protocols like SSLv3 or TLS 1.0
• Weak cipher suites
• Self-signed certificates
• Insecure redirects
• Incomplete HSTS policies

---

📉 Why is Weak SSL TLS Configuration in Laravel Dangerous?

1. Data Interception – Unencrypted data can be sniffed by attackers.
2. Spoofing – Without validation, malicious actors can impersonate your server.
3. SEO Penalty – Search engines lower rankings for insecure sites.
4. Trust Issues – Browsers warn users about insecure connections.

✅ Step-by-Step Laravel Fixes with Code Examples

Let’s get straight into it. Here’s how to fix weak SSL/TLS configuration in Laravel.

---

1. Force HTTPS Using Middleware

Laravel provides a built-in middleware to redirect all HTTP traffic to HTTPS.

// In App\Http\Middleware\RedirectToHttps.php
public function handle($request, Closure $next)
{
    if (!$request->secure()) {
        return redirect()->secure($request->getRequestUri());
    }

    return $next($request);
}

Then, register the middleware in app/Http/Kernel.php.

protected $middleware = [
    \App\Http\Middleware\RedirectToHttps::class,
];

💡 This prevents downgrade attacks and ensures all connections are encrypted.

---

2. Use HSTS Headers

HSTS (HTTP Strict Transport Security) forces browsers to use HTTPS. Add it in Laravel using middleware:

public function handle($request, Closure $next)
{
    $response = $next($request);
    $response->headers->set('Strict-Transport-Security', 'max-age=31536000; includeSubDomains; preload');
    return $response;
}

---

3. Disable Old SSL/TLS Protocols on Server

Update your Nginx or Apache config:

Nginx example:

ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384';

Apache example:

SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLCipherSuite HIGH:!aNULL:!MD5

---

4. Use Valid SSL Certificates

Use certificates from trusted providers like Let’s Encrypt or Cloudflare.

sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com

---

5. Verify HTTPS in Laravel Configuration

Ensure your .env file and config/app.php recognize secure URLs.

APP_URL=https://yourdomain.com

'url' => env('APP_URL', 'https://yourdomain.com'),

---

6. Use Laravel’s TrustProxies

Laravel doesn’t trust proxies by default, which may cause HTTPS detection issues.

Install the middleware:

use Illuminate\Http\Request;
use Fideloper\Proxy\TrustProxies;

class AppServiceProvider extends ServiceProvider
{
    protected $proxies = '*';
}

---

7. Secure Cookies

Update your session configuration in config/session.php:

'secure' => env('SESSION_SECURE_COOKIE', true),

Set in .env:

SESSION_SECURE_COOKIE=true

---

8. Enable CSP and XSS Protection

These aren’t SSL-related directly, but go hand-in-hand with secure transmission.

public function handle($request, Closure $next)
{
    $response = $next($request);
    $response->headers->set('Content-Security-Policy', "default-src 'self'");
    $response->headers->set('X-XSS-Protection', '1; mode=block');
    return $response;
}

---

9. Test Your Laravel App’s SSL/TLS Security
