SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Improvised XSS hunting leads to incomplete results, often requiring multiple prompts and a waste of tokens and time. This Skill eliminates improvisation by providing a comprehensive, structured methodology for XSS hunting.

Core Features & Use Cases

  • Structured XSS Methodology: Includes reflected, stored, DOM-based, blind, and mutation XSS testing.
  • CSP Bypass Techniques: Explores ways to bypass Content-Security-Policy restrictions.
  • Impact Escalation Demonstration: Shows how XSS vulnerabilities can be exploited for real-world impact such as cookie theft and CSRF attacks.

Quick Start

Install and add the xss-hunter skill into the appropriate agent for testing XSS vulnerabilities in web applications.

FAQPage Schema
How do I test for DOM-based and mutation XSS vulnerabilities in web applications?

XSS testing for DOM-based and mutation vectors requires a structured methodology that executes scripts to handle different web contexts, eliminating improvised testing and ensuring comprehensive vulnerability discovery.

What is the best way to demonstrate the real-world impact of an XSS vulnerability?

Impact escalation for XSS vulnerabilities demonstrates real-world impact by showing how exploits achieve cookie theft and execute CSRF attacks, proving the severity of the discovered cross-site scripting flaw.

How do I bypass Content-Security-Policy restrictions during a pentest?

CSP bypass strategies explore specific techniques to circumvent Content-Security-Policy restrictions during a pentest, allowing you to execute payloads and confirm XSS vulnerabilities within protected web contexts.

How do I carry out a comprehensive XSS hunting methodology without wasting tokens?

A comprehensive XSS hunting methodology covers reflected, stored, DOM-based, blind, and mutation XSS testing, eliminating improvisation to deliver complete results without requiring multiple prompts.

Do I need script execution capabilities to test for blind XSS?

Yes, testing for blind XSS requires the ability to execute scripts and handle different web contexts, as the methodology relies on script execution to confirm payload firing outside the immediate application interface.

Why does my improvised XSS testing lead to incomplete vulnerability discovery results?

Improvised XSS testing leads to incomplete results because it lacks a structured methodology, causing missed vectors and wasted tokens compared to a battle-tested approach for cross-site scripting discovery.
