CVE-2022-25413Public exploitNetwork attack vector

Stored script execution via crafted page tags

Published Feb 28, 2022 · Updated Aug 3, 2024

Stored XSS in MaxSite CMS 108 allows remote authenticated users to execute script in an administrator's browser via crafted page tags. The page editor stores the f_tags value in the database and later renders it without neutralizing HTML event-handler markup. An authenticated user must save a crafted tag, and an administrator must revisit the affected page-edit view; resulting script runs in that administrator's session.
