CVE-2023-1030Public exploitNetwork attack vector

Reflected XSS via un login parameter

Published Feb 24, 2023 · Updated Apr 3, 2025

Reflected XSS in Online Boat Reservation System 1.0 allows remote authenticated users to execute script via the login username. The /boat/login.php POST handler reflects the un parameter into its response without neutralizing executable browser markup. A valid account and interaction by another user are required, and the demonstrated consequence is attacker-controlled script execution in that user’s browser session.
