Fraudulent Store Warning


It has come to our attention that there are several websites claiming to offer significantly discounted Canon products at 90% off or more. These websites are designed to look like our official Canon Store and we believe they are not legitimate, aimed only at confusing and deceiving our customers into sharing personal and financial data. We advise our customers to be vigilant when shopping online with Canon and other retailers.


To recognise the official Canon online store, all Canon stores across Europe have a similar domain name: https://store.canon.xx
The final characters change per each country. For example: https://store.canon.fr & https://store.canon.co.uk.

Windows Print Spooler Remote Code Execution Vulnerability – Updated 16 November 2021

A vulnerability with Microsoft Windows Print Spooler was discovered earlier this year, which has been referred to as “PrintNightmare”. The vulnerability allows hackers to take control users' Windows systems under certain conditions.

While this may affect the users of Canon devices, this is the result of a flaw within Microsoft software rather than any issue with Canon's products or software. Specifically, the issue lies with the print spooler functionality which is installed on every Windows Server and Windows desktop.

Microsoft announced that these vulnerabilities were resolved within the Microsoft July 6th Security Update, available through Windows Update or by downloading and installing KB5004945. Microsoft recommends that IT teams apply this update immediately to help prevent intrusions related to these vulnerabilities. For full information from Microsoft on the matter, please visit https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527

In addition to Microsoft’s advice to install the updates, we also recommend you secure your system by confirming that the following registry settings are set to 0 (zero) or are not defined (Note: these registry keys do not exist by default, and therefore are already at the secure setting). You should also check that your Group Policy settings are correct:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\PointAndPrint
  • NoWarningNoElevationOnInstall = 0 (DWORD) or not defined (default setting)
  • UpdatePromptSettings = 0 (DWORD) or not defined (default setting)

Having the ‘NoWarningNoElevationOnInstall’ registry key set to 1 reduces your system security posture.

We advise that your IT team continues to monitor the Microsoft support site to ensure that all applicable underlying operating system patches are applied.

 

“AMNESIA:33”: Embedded TCP/IP Stacks vulnerabilities – Updated 10 December 2020

Following investigation, we have determined that no imageRUNNER, imageRUNNER ADVANCE or i-SENSYS products are affected by this vulnerability. We are continuing our investigation across the Canon product range and will update this article as further information becomes available.

 

uniFLOW MicroMIND vulnerability – Updated 08 December 2020

It has been brought to our attention by the 'Federal Office for Information Security' (BSI) that the network implementation within the microMIND is vulnerable to a number of exploits. These vulnerabilities were discovered by 'Forescout Technologies', researchers Jos Wetzels, Stanislav Dashevskyi, Amine Amri, and Daniel dos Santos.

The microMIND utilises the uIP open-source network stack, https://en.wikipedia.org/wiki/UIP_(micro_IP) used by thousands of companies to network enable their software/hardware. The researchers found that if exploited these vulnerabilities could result in a DoS attack taking the device offline or performing Remote Code Execution (RCE) on the microMIND itself. To address these vulnerabilities NT-ware has released a new firmware that addresses all reported issues. At the time of writing this security bulletin there are no known exploits targeting the microMIND.

Exploit name/link: AMNESIA:33, https://www.forescout.com/amnesia33/

CVE's addressed in this firmware are: CVE-2020-13988, CVE-2020-13987, CVE-2020-17438, CVE-2020-17437

CVE's not related to the MicroMIND implementation of the uIP Stack: CVE-2020-17440, CVE-2020-17439, CVE-2020-24334, CVE-2020-24335

Affected uniFLOW microMIND Firmware: version 2.0.9 and earlier or delivered prior to October 2020.

Mitigation/Action: If you have an affected microMIND please contact your Canon representative to arrange upgrading the firmware.

 

Canon Laser and Small Office Multifunctional Printer related vulnerabilities with the IP Stack – Updated 01 October 2020

A cyber security company headquartered in Israel, SCADAfence Ltd., drew our attention to a vulnerability related to IP stack protocol, which is used by Canon Laser Printer and Small Office Multifunctional Printer. Please refer to CVE-2020-16849 for details.

The potential exists for a third-party attack on the device when it is connected to a network allowing fragments of the “Address book” or/and “administrator password” to be acquired through an unsecured network. It should be noted that when HTTPS is used for the communication of Remote UI, data is secured by encryption.

To date, there have been no confirmed cases of these vulnerabilities being exploited to cause harm. However, in order to ensure that our customers can use our products securely, new firmware will be available for the following products:

i-SENSYS MF Series
MF113W
MF212W/MF216N/MF217W
MF226DN/MF229DW
MF231/MF232W/MF237W
MF244DW/MF247DW/MF249DW
MF264DW/MF267DW/MF269DW
MF4570DN/MF4580DN
MF4780W
MF4870DN/MF4890DW

i-SENSYS LBP Series
LBP113W
LBP151DW
LBP162DW

imageRUNNER Series
IR2202N
IR2204N/IR2204F
IR2206N/IR2206IF

Please refer to the User Manual for details on how to update firmware.
We recommend that a private IP address is used for products and use network parameter controls such as the use of a firewall or Wi-Fi router that can restrict network access. The ‘Security for Products Connected to a Network’ section further down on this page gives some additional guidance.

 

“Ripple20”: Multiple Vulnerabilities Identified in the TCP/IP Stack – Updated 30 September 2020

After investigation into the ‘Ripple20’ vulnerability, there has been no identified issue with Canon printer products.

 

Security provided by eight character numerical passwords – Added 06 March 2020

Whilst Canon’s wireless function password complies with the current WPA standard, we are aware that the security provided by eight-character numerical passwords isn’t considered to be as strong as it used to be. With this in mind, we recommend that in environments where wireless security is a concern, such as a public location, Canon equipment should always be connected to infrastructure Wi-Fi deployment. We take security seriously - we are updating the Wi-Fi security configurations across our products to help you remain secure and any update will be published on these pages. Canon would like to thank REDTEAM.PL for drawing our attention to the changing nature of password security and its impact on the market.

 

ImageRUNNER ADVANCE Syslog and Log events – Added 20 February 2020

The imageRUNNER ADVANCE software platform version 3.8 and later introduced the Syslog protocol (compliant with RFC 5424, RFC 5425 and RFC 5426) near real-time event messaging functionality adding to existing device logging increasing visibility of device and device security events. This builds upon the device logging capability allowing connection to an existing security information event management (SIEM) or Syslog server. The ‘SIEM_spec’ document given below details of the messages types and log data that can be generated.
