CVE-2021-4232Network attack vector

Browser script execution via unneutralized ticket input

Published May 26, 2022 · Updated Apr 15, 2025

Cross-site scripting in PHPGurukul Zoo Management System 1.0 allows remote attackers to execute script in another user's browser. The admin/manage-ticket.php page places attacker-controlled input into an HTML response without neutralizing script markup; the public record does not identify the parameter or function. Exploitation requires a user to load the crafted content, allowing the script to read or alter data available to that browser session.
