XSS Payload Generator

A powerful, customizable XSS Payload Generator designed to help ethical hackers, penetration testers, and cybersecurity enthusiasts understand Cross-Site Scripting (XSS) vulnerabilities and test Web Application Firewalls (WAFs). This tool is ideal for learning, demonstrating attack scenarios, and creating advanced XSS payloads for testing in secure environments.

Features

Dynamic Payload Generation

• Choose from a variety of HTML tags, including:

  • <img>
  • <svg>
  • <script>
  • <iframe>
  • <a>
  • <div>

• Select common event handlers, such as:

  • onerror
  • onload
  • onclick
  • onmouseover
  • onfocus

Advanced Encoding and Obfuscation

Encode payloads to evade detection:

• URL Encoding
• Base64 Encoding
• Hexadecimal Encoding Enable obfuscation to bypass basic security filters by injecting comments and breaking up code.

User-Friendly Interface

• Clean, responsive design for easy use on any device.
• Real-time payload generation with a preview feature.

How It Works

1. Select a Tag:

• Choose an HTML tag (e.g., or ) that supports JavaScript event handlers.

2. Choose an Event Handler:

• Select an event that triggers JavaScript (e.g., onerror, onload).

3. Enter a JavaScript Payload:

• Input the JavaScript code you want to execute (e.g., alert('XSS')).

4. Select Encoding:

• Choose an encoding method to obfuscate your payload.

5. Enable Obfuscation (Optional):

• Add random comments or spaces to further evade detection.

6. Generate Payload:

• Click the button to generate the payload, which will be displayed in the output box.

Frequently Asked Questions (FAQ)

1. What is XSS?

• Cross-Site Scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into trusted websites, affecting users who interact with those sites.

2. How can I practice safely?

• Use this tool in isolated environments, such as:
  • Virtual Machines
  • Local Test Servers
  • Penetration Testing Labs like Hack The Box or TryHackMe.

3. How do I protect against XSS?

• Sanitize and validate user inputs.
• Use Content Security Policy (CSP) headers.
• Encode outputs properly.

Roadmap

Future enhancements for this project include:

• Adding predefined XSS payload templates.
• Supporting multi-step obfuscation techniques.
• Allowing users to save and export payloads.
• Expanding to other vulnerability types (e.g., SQL Injection, LFI).
