SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps identify Cross-Site Scripting (XSS) vulnerabilities in web applications by injecting JavaScript payloads into various contexts and testing for client-side code execution and session hijacking.

Core Features & Use Cases

  • XSS Testing: Injects JavaScript payloads into reflected, stored, and DOM-based contexts.
  • Vulnerability Identification: Identifies all injection points and output contexts.
  • Payload Crafting: Crafts context-appropriate payloads and bypasses sanitization and CSP protections.
  • Use Cases: Used for OWASP WSTG testing, input sanitization evaluation, and CSP effectiveness assessment.

Quick Start

Execute the 'xss-test' command within the Skill to start testing for XSS vulnerabilities in the target application.

FAQPage Schema
How do I test for XSS vulnerabilities in a web application?▼

This Skill tests for XSS vulnerabilities by injecting JavaScript payloads into reflected, stored, and DOM-based contexts, verifying client-side code execution and identifying potential session hijacking risks during penetration testing.

What is the best way to check if my input sanitization prevents cross-site scripting?▼

To evaluate input sanitization, this Skill crafts context-appropriate JavaScript payloads designed to bypass existing protections, identifying injection points and verifying if your filters successfully mitigate cross-site scripting attempts.

Can I use this for OWASP WSTG penetration testing and CSP effectiveness assessment?▼

Yes, this Skill supports OWASP WSTG penetration testing and CSP effectiveness assessment by injecting payloads to verify if your Content Security Policy rules successfully prevent cross-site scripting execution.

Does this XSS testing approach work for stored, reflected, and DOM-based contexts?▼

Yes, this Skill handles stored, reflected, and DOM-based contexts by identifying all injection points and output contexts, injecting JavaScript payloads to verify cross-site scripting vulnerabilities and their overall impact.

How do I start a security audit to identify cross-site scripting injection points?▼

You start a security audit by executing the 'xss-test' command, which initiates payload injection and vulnerability verification to detect cross-site scripting flaws in your target web application.
