is there a wider tumblr tag/blogs for ethical hacking and cybersecurity? i really got into this hobby and might work to get a job in it.

the codeblr/progblr tags seem to be mostly people learning coding

if you regularly post about it please let me know too

Prevent Command Injection in Symfony: Secure Your Code

Symfony is a powerful PHP framework trusted by thousands of developers, but like any framework, it's not immune to security threats. One of the most dangerous—and often overlooked—threats is a Command Injection Attack.

In this blog post, we’ll break down what a command injection attack is, how it can be exploited in a Symfony application, and—most importantly—how to prevent it. We’ll also include code examples and offer you a Website Vulnerability Scanner online free to scan your website for vulnerabilities like this one.

➡️ Visit Our Blog for More Cybersecurity Posts: 🔗 https://www.pentesttesting.com/blog/

🧨 What is Command Injection?

Command Injection is a type of security vulnerability that allows attackers to execute arbitrary system commands on your server. If user input is improperly sanitized, attackers can exploit functions like exec(), system(), or shell_exec() in PHP.

This can lead to:

Data breaches

Server hijacking

Total application compromise

🐘 Symfony Command Injection Example

Let’s start with a naive Symfony controller that might fall victim to command injection.

❌ Vulnerable Symfony Code

// src/Controller/BackupController.php namespace App\Controller; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; use Symfony\Bundle\FrameworkBundle\Controller\AbstractController; class BackupController extends AbstractController { public function backupDatabase(Request $request): Response { $filename = $request->query->get('filename'); // ⚠️ Dangerous input $output = shell_exec("mysqldump -u root -psecret mydb > /backups/{$filename}"); return new Response("Backup created: $filename"); } }

If an attacker sets filename=backup.sql;rm -rf /, this code could delete your entire server. Yikes!

🔐 Secure It With Escaping & Whitelisting

Let’s see how we can secure this.

✅ Safe Symfony Version

public function backupDatabase(Request $request): Response { $filename = $request->query->get('filename'); // Sanitize the filename using a whitelist or regex if (!preg_match('/^[\w\-\.]+$/', $filename)) { return new Response("Invalid filename", 400); } $safePath = escapeshellarg("/backups/" . $filename); $output = shell_exec("mysqldump -u root - psecret mydb > $safePath"); return new Response("Backup created: $filename"); }

By using escapeshellarg() and validating the input, we reduce the risk significantly.

Dear My Arch Debian Nemesis @kali-official,

Naturally, and this USB stick's not big enough for the both of us (it's a 4gb usb2.0 😬). But just because we are rivals, that's no excuse to misgender you.

[lostlibrariangirl]

Hello guys! How are you doing? I am trying to keep up with Angular studies, plus I am doing a short Pentest classes in order to understand it a little bit more, as I requested some Pentests at work for a special team inside the company. It is very interesting, to understand the vulnerabilities that can occurs, and how to think about them while we are creating the architecture of applications, databases, etc. I will start new Spring boot courses as soon as possible too. Yesterday I started for real in the architecture team at work, and I am terrified as I already have some deadlines I must look forward to things I am not an expert yet (✖﹏✖) Well, I will do my best, and ask for help whenever I need (≖͞_≖̥) Keep studying, keep pursuing your dreams!

Symfony Clickjacking Prevention Guide

Clickjacking is a deceptive technique where attackers trick users into clicking on hidden elements, potentially leading to unauthorized actions. As a Symfony developer, it's crucial to implement measures to prevent such vulnerabilities.

🔍 Understanding Clickjacking

Clickjacking involves embedding a transparent iframe over a legitimate webpage, deceiving users into interacting with hidden content. This can lead to unauthorized actions, such as changing account settings or initiating transactions.

🛠️ Implementing X-Frame-Options in Symfony

The X-Frame-Options HTTP header is a primary defense against clickjacking. It controls whether a browser should be allowed to render a page in a <frame>, <iframe>, <embed>, or <object> tag.

Method 1: Using an Event Subscriber

Create an event subscriber to add the X-Frame-Options header to all responses:

// src/EventSubscriber/ClickjackingProtectionSubscriber.php namespace App\EventSubscriber; use Symfony\Component\EventDispatcher\EventSubscriberInterface; use Symfony\Component\HttpKernel\Event\ResponseEvent; use Symfony\Component\HttpKernel\KernelEvents; class ClickjackingProtectionSubscriber implements EventSubscriberInterface { public static function getSubscribedEvents() { return [ KernelEvents::RESPONSE => 'onKernelResponse', ]; } public function onKernelResponse(ResponseEvent $event) { $response = $event->getResponse(); $response->headers->set('X-Frame-Options', 'DENY'); } }

This approach ensures that all responses include the X-Frame-Options header, preventing the page from being embedded in frames or iframes.

Method 2: Using NelmioSecurityBundle

The NelmioSecurityBundle provides additional security features for Symfony applications, including clickjacking protection.

Install the bundle:

composer require nelmio/security-bundle

Configure the bundle in config/packages/nelmio_security.yaml:

nelmio_security: clickjacking: paths: '^/.*': DENY

This configuration adds the X-Frame-Options: DENY header to all responses, preventing the site from being embedded in frames or iframes.

🧪 Testing Your Application

To ensure your application is protected against clickjacking, use our Website Vulnerability Scanner. This tool scans your website for common vulnerabilities, including missing or misconfigured X-Frame-Options headers.

After scanning for a Website Security check, you'll receive a detailed report highlighting any security issues:

🔒 Enhancing Security with Content Security Policy (CSP)

While X-Frame-Options is effective, modern browsers support the more flexible Content-Security-Policy (CSP) header, which provides granular control over framing.

Add the following header to your responses:

$response->headers->set('Content-Security-Policy', "frame-ancestors 'none';");

This directive prevents any domain from embedding your content, offering robust protection against clickjacking.

🧰 Additional Security Measures

CSRF Protection: Ensure that all forms include CSRF tokens to prevent cross-site request forgery attacks.

Regular Updates: Keep Symfony and all dependencies up to date to patch known vulnerabilities.

Security Audits: Conduct regular security audits to identify and address potential vulnerabilities.
