Description
Camaleon CMS before 2.9.2 contains a missing authorization vulnerability in Admin::MediaController that allows low-privileged authenticated users to bypass the role-based Media permission. Attackers can POST to /admin/media/upload to store files, read private media via download_private_file, and use crop with saved_avatar to change other users' avatars.
A missing authorization vulnerability has been identified in Camaleon CMS versions prior to 2.9.2, specifically within the Admin::MediaController. This vulnerability allows low-privileged authenticated users to bypass the role-based media permissions. Exploitation of this issue enables users to upload files through the '/admin/media/upload' endpoint, access private media via the 'download_private_file' action, and manipulate other users' avatars by using the 'crop' action with 'saved_avatar'.
Users are advised to upgrade to Camaleon CMS version 2.9.2 or later, where this vulnerability has been addressed. After upgrading, review user roles in the admin interface to ensure that the 'media' permission is correctly assigned.
