A few older Lexmark devices did not have the ability to restrict access to the SE and shortcut menus. Therefore unauthenticated users could access this information.
A few older Lexmark devices did not have the ability to restrict access to the SE and shortcut menus. Therefore unauthenticated users could access the information in these menus. The shortcut menu contains information on the shortcuts configured in the device; the SE menu contains information used by Lexmark to diagnose device errors. Neither of these menus provides access to print/scan data.
Updated firmware is available that provides the ability to restrict access to the SE and Shortcut menus.
