CVE-2024-22493Public exploitNetwork attack vector

Stored script execution via guestbook content injection

Published Jan 12, 2024 · Updated Sep 10, 2024

Stored XSS in JFinalCMS 5.0.0 allows remote authenticated users to execute script in another user’s browser through guestbook content. The /gusetbook/save handler stores the content parameter without neutralizing attacker-supplied HTML or script before a guestbook page renders it. Exploitation requires low-privileged access and a user to view the stored entry, exposing that user’s page data and actions to the injected script.
