Web cache poisoning via ambiguous requests - Lab#03

In this walkthrough, we exploit Web Cache Poisoning via Ambiguous Requests. This vulnerability occurs when inconsistencies between the cache and the back-end server allow malicious input to be stored and served to users. You’ll learn how to: Craft ambiguous HTTP requests Exploit discrepancies between caching behavior and server interpretation Inject JavaScript to trigger alert(document.cookie) in a victim’s browser 📌 Lab Objective: Poison the cache so that a victim visiting the home page triggers a JavaScript alert with their cookie. 🧠 Skill Level: Advanced 💡 Key Concepts: Cache keys, header manipulation, request normalization ⚠️ This is a real-world technique used in targeting shared cache environments. Practice responsibly and use only in authorized environments. #WebSecurity #CachePoisoning #PortSwigger #BugBounty #WebSecurityAcademy #EthicalHacking #CyberSecurity #BurpSuite #XSS #JavaScriptInjection #OWASP #AmbiguousRequests #InfoSec #ctfinal
