Detail of the vulnerability

Recently a Denial of Service (DoS) vulnerability was found on our multi-function and single-function printers, according to which, users with network access can sending commands to selected FUJIFILM Business Innovation devices through an unsecured network which can potentially make the machine stop with error code.
However, this vulnerability was found to have no impact on the information stored on these devices.
Vulnerability is simply leading to productivity loss by means of device needs to be turned off and on (to recover), when a system fault error (116-324) is displayed on the operational panel.


The updated firmware is to be downloaded through the network using the remote maintenance service or to be applied by customer service engineers.
For customers who setup auto-download of firmware by EP-BB* 1 maintenance contract, the device firmware will be serially upgraded by EP-BB feature after the release of latest firmware. For other customers who don’t have an EP-BB maintenance contract, please contact “FUJIFILM Business Innovation customer support center” described at the end of the page.

  • * 1 Electronic Partnership Broad Band (EP-BB) enabling Smart Remote Service


In order to mitigate the potential risks from this vulnerability, we would advise our customers to implement following workarounds until next firmware fix is released.

  • Please see, your FUJIFILM Business Innovation multi-function printers or single-function printers on the network are protected by the firewall etc.
  • If external access from internet is permitted, then please consider permitting the access to specific IP address only or use VPN to connect.
