CVE-2023-5304Network attack vector

Browser script execution via unneutralized message parameter

Published Sep 30, 2023 · Updated Aug 2, 2024

Cross-site scripting in PHPGurukul Online Banquet Booking System 1.0 allows remote attackers to execute script through the message parameter. The Service Booking handler in /book-services.php inserts the message value into generated page content without neutralizing executable markup. A victim must load the affected response; the injected script then runs in that user's browser under the application's origin, enabling limited page-data access and content changes.
