The Layout module in Liferay Portal v7.3.3 through v7.4.3.34, and Liferay DXP 7.3 before update 10, and 7.4 before update 35 does not check user permission before showing the preview of a "Content Page" type page, allowing attackers to view unpublished "Content Page" pages via URL manipulation.

Root Cause Analysis

The vulnerability stems from missing authorization checks in the layout preview functionality. The PreviewLayoutMVCResourceCommand is a core component responsible for handling preview requests in Liferay's Layout module. Since the advisory specifically mentions URL manipulation to access unpublished content pages, this MVC resource command would be the logical entry point that processes preview requests. The vulnerability pattern matches typical missing authorization scenarios where resource commands fail to verify VIEW permissions before rendering protected content. The high confidence comes from the direct correlation between the module mentioned (Layout), the attack vector (URL manipulation for previews), and Liferay's standard MVC command pattern for handling such requests.
