Lab: Reflected XSS into HTML context with most tags and attributes blocked


This lab contains a reflected cross-site scripting vulnerability in the search functionality but uses a web application firewall (WAF) to protect against common XSS vectors.

To solve the lab, perform a cross-site scripting attack that bypasses the WAF and alerts document.cookie.


Your solution must not require any user interaction. Manually triggering an alert in your own browser will not solve the lab.
