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

PRACTITIONER

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.

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