Vulnerability
This is an escalation of privileges attack that can be used by anonymous users to gain access to a Plone site's administration controls, view unpublished content, create new content and modify a site's skin. The sandbox protecting access to the underlying system is still in place, and it does not grant access to other applications running on the same Zope instance.
