CVE-2024-3178Network attack vector

Stored XSS via unescaped search preset names

Published Apr 3, 2024 · Updated Aug 30, 2024

Stored XSS in Concrete CMS before 8.5.16 and 9.0.0 through 9.2.7 allows remote authenticated users to execute script via search preset names. The file-search preset edit and delete paths insert stored preset names into form fields and status messages without HTML escaping. Administrator access is required to save a malicious filter, and another user must interact with that preset for the script to run in that user's browser session.
