Overview

Some Dell products allow the creation of pre-defined email addresses ("shortcuts") to streamline the use of functions such as "Scan to Email". On vulnerable products it is possible to craft a shortcut that contains hidden email addresses that are not displayed to the user via the operator panel or on the embedded web server. In the event a hidden email address is added, anyone making use of the shortcut would have their scanned data sent to additional email addresses they were unaware of, although a close examination of the header of the delivered email would reveal the additional email addresses.

Workarounds

Restrict access to the manage shortcuts functionality to trusted personnel. The "Manage Shortcuts at the Device" and "Manage Shortcuts Remotely" function access controls can be utilized to restrict the ability to create and edit email shortcuts to authenticated and authorized personnel. For more information see your product’s User Guide or the Embedded Web Server Administrator’s Guide.
