XSS - Stored Scanner
Identifies stored XSS vulnerabilities where malicious scripts persist in the application.
What is XSS - Stored?
Stored XSS (also called persistent XSS) occurs when malicious scripts are permanently stored on the target server—in a database, comment field, forum post, or user profile. Every user who views the affected content has the script execute in their browser without any additional action.
Why is This Important?
Stored XSS is the most dangerous XSS variant because it affects all users who view the infected content, not just those who click a malicious link. A single injection can compromise thousands of users, steal admin credentials, spread malware, or deface the entire website.
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.

Frequently Asked Questions
Why is stored XSS more dangerous than reflected?
Stored XSS affects every visitor automatically without requiring them to click anything. One injection in a popular page could compromise all users who view it.
Where is stored XSS commonly found?
Comment sections, user profiles, forum posts, product reviews, message boards, support tickets, and any feature where user content is saved and displayed to others.
Can stored XSS affect admin users?
Yes, and this is particularly dangerous. If an admin views user-generated content containing XSS, attackers can steal admin sessions and take over the entire application.
How do worms spread via stored XSS?
Self-propagating XSS worms inject code that makes victims unknowingly post the same malicious content, creating viral spread. The Samy MySpace worm infected over 1 million users in 24 hours.
