CVE-2023-4112Public exploitNetwork attack vector

Reflected XSS via unsanitized index path

Published Aug 3, 2023 · Updated Aug 2, 2024

Reflected XSS in /index.php in QuanticaLabs Shuttle Booking Software 1.0 allows remote attackers to execute script through a crafted URL. The application inserts an attacker-controlled path suffix after index.php into the admin login error response without neutralizing HTML or script markup. A victim must open the crafted link; the injected script then runs in the site context and can alter displayed content or access browser-resident session data.
