Technical details

A missing authorization vulnerability exists in Pimcore's WebDAV implementation within the CoreBundle. The WebDAVController fails to attach an authentication plugin, and the Tree::move() method in the WebDAV model performs asset mutations (including deletion of source assets during overwrites) before verifying user permissions or session validity. An attacker knowing the paths of two assets in the same directory can trigger a MOVE request that results in the deletion of the source asset, even if the request eventually fails due to a null user object. This allows unauthenticated remote attackers to destroy data or authenticated low-privileged users to bypass granular asset permissions (rename, delete, create, or publish). The issue is resolved in versions 11.5.17 (LTS) and 12.3.7.
