CVE-2022-42749Public exploitNetwork attack vector

Account takeover via reflected page parameter

Published Nov 3, 2022 · Updated May 5, 2025

Reflected XSS in CandidATS 3.0.0 allows remote attackers to steal administrator session cookies through the ajax.php page parameter. The endpoint reflects the unvalidated page value into its response, causing a victim's browser to execute attacker-supplied script in the site's origin. Exploitation requires an administrator to open a malicious link; the demonstrated consequence is account takeover through session-cookie theft.
