An information disclosure vulnerability in Kentico Xperience allows attackers to view sensitive stack trace details via Portal Engine form control error messages. Detailed error messages can expose internal system information and potentially reveal implementation details to unauthorized users.

An information disclosure vulnerability in Kentico Xperience allows authenticated users to view sensitive system objects through the live site widget properties dialog. Attackers can exploit this vulnerability to access unauthorized system information without proper access controls.

DISPUTED Kentico 11 through 12 lets attackers upload and explore files without authentication via the cmsmodules/medialibrary/formcontrols/liveselectors/insertimageormedia/tabsmedia.aspx URI. NOTE: The vendor disputes the report because the researcher did not configure the media library permissions correctly. The vendor states that by default all users can read/modify/upload files, and it’s up to the administrator to decide who should have access to the media library and set the permissions accordingly. See the vendor documentation in the references for more information.
