Otkriven je sigurnosni nedostatak u paketu HP MFP Digital Sending Software za operacijske sustave Windows. Ovaj paket se koristi za slanje skeniranih dokumenata na različita odredišta poput FTP poslužitelja, pisača ili e-mail adresu. Nisu objavljeni uzroci samog propusta, ali je poznato da ga lokalni napadač može iskoristiti za pristup uređajima preko Digital Sending Software paketa bez autentikacije. Za sada nije dostupna nadogradnja kojom se otklanja nedostatak, nego se preporuča uključivanje autentikacije pomoću "Configuration Template" funkcionalnosti.
