Web Cache Poisoning Scanner
Tests for web cache poisoning vulnerabilities in CDN and cache layers.
What is Web Cache Poisoning?
Web cache poisoning occurs when attackers manipulate cache keys to store malicious responses that are then served to other users. By finding unkeyed inputs (headers, cookies) that affect response content, attackers can poison caches to serve XSS, redirect users, or modify content for all visitors.
Why is This Important?
Cache poisoning scales attacks to affect all users receiving cached responses, not just individual victims. A single poisoned response can deliver XSS, phishing content, or malware to thousands of users until the cache expires.
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
How does cache poisoning work?
Attackers find inputs that affect the response but aren't included in the cache key (unkeyed inputs). They craft requests that produce malicious cached responses served to all users.
What are common unkeyed inputs?
Headers like X-Forwarded-Host, X-Forwarded-Proto, X-Original-URL, cookies, and any custom headers the application processes but the cache doesn't include in keys.
How long do poisoned entries persist?
Until the cache TTL expires. For heavily cached static content, this could be hours or days. Some attacks target cache busting to make poisoned content persist longer.
How do I prevent cache poisoning?
Include all inputs that affect response in cache keys, validate Host and forwarding headers, and use cache-control headers appropriately. Consider what inputs shouldn't be cached at all.
