CVE-2023-37063Network attack vector

Stored XSS via unvalidated career and promotion names

Published Jul 7, 2023 · Updated Nov 13, 2024

Stored XSS in Chamilo LMS 1.11.0 through 1.11.20 allows remote authenticated users to execute script in another user's browser. The career.lib.php and promotion.lib.php forms create name fields with generic addElement text controls; the patch replaces them with validating addText calls. Administrator access is required to save the payload, and another user must view the affected content; execution is limited to that viewer's session.
