SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the critical need to identify and demonstrate Cross-Site Scripting (XSS) and HTML Injection vulnerabilities in web applications, protecting against session hijacking and data breaches.

Core Features & Use Cases

  • Vulnerability Detection: Systematically identifies input reflection points and tests for XSS/HTMLi flaws across stored, reflected, and DOM-based vectors.
  • Exploitation Techniques: Provides payloads for cookie stealing, session hijacking, and phishing.
  • Filter Bypass: Offers methods to circumvent common security filters and WAFs.
  • Use Case: A security analyst can use this skill to thoroughly test a web application's user-submitted content fields for vulnerabilities before deployment, ensuring robust security.

Quick Start

Use the xss-html-injection skill to test the search functionality of 'https://example.com' for reflected XSS vulnerabilities.

FAQPage Schema
How do I test web applications for reflected and stored XSS vulnerabilities?▼

This Skill detects XSS vulnerabilities by systematically identifying input reflection points and testing stored, reflected, and DOM-based vectors to prevent session hijacking and data breaches.

What is the best way to bypass WAF filters during HTML injection testing?▼

The best way to bypass WAF filters during HTML injection testing is to use specific payload variations designed to circumvent common security filters, allowing successful exploitation of user-submitted content fields.

Can I use this to generate payloads for cookie stealing and phishing simulations?▼

Yes, it provides specific exploitation techniques and payloads for cookie stealing, session hijacking, and phishing to demonstrate client-side injection attack vectors.

Does this cover DOM-based Cross-Site Scripting assessment end to end?▼

Yes, it performs comprehensive client-side injection vulnerability assessments covering DOM-based XSS, including filter bypass techniques and actionable remediation advice for web applications.

How do I identify input reflection points for HTML injection flaws?▼

You identify input reflection points by performing comprehensive vulnerability assessments that systematically test user-submitted content fields for HTML injection flaws across multiple attack vectors.
