Technical details

A reflected cross-site scripting (XSS) vulnerability exists in the 'wallpaper.php' script within the web-based management interface of several Barco ClickShare Base Unit models. The vulnerability is caused by insufficient sanitization of user-supplied input, allowing a remote, unauthenticated attacker to execute arbitrary JavaScript in the context of a victim's browser session. Exploitation requires a user to interact with a malicious link or visit a compromised website while authenticated to the ClickShare device. Successful exploitation can lead to session hijacking or unauthorized configuration changes. The issue is resolved in firmware versions 01.09.03 (CSC-1), 01.06.02 (CSM-1), and 01.03.02 (CSE-200).
