CVE-2023-5842Network attack vector

Authenticated stored XSS via incomplete event filtering

Published Oct 30, 2023 · Updated Sep 6, 2024

Stored cross-site scripting in Dolibarr ERP & CRM before 16.0.5 allows remote authenticated users to execute script in other users' browsers. The htdocs/main.inc.php testSqlAndScriptInject filter failed to inspect a tag-stripped value for several event-handler names, allowing crafted stored input to bypass checks and render executable HTML or JavaScript. Exploitation requires a user with the privileges to submit persistent content and another user to view the affected page; impact is script execution in that viewer's browser.
