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:
The final characters change per each country. For example: &

RSA key generation vulnerability for Enterprise/Small Office Multifunction Printers, Laser Printers and Inkjet Printers – 04 April 2022

A vulnerability had been confirmed in the RSA key generating process in the Cryptographic library mounted on Canon’s Enterprise/Small Office Multifunction Printers and Laser Printers/Inkjet Printers. A full list of affected products is included below.

The risk of this vulnerability is the possibility of private key for RSA public key being estimated by someone, due to issues in the generation process of RSA key pair.
If the RSA key pair is used for TLS or IPSec, is generated by a Cryptographic library with this vulnerability, this RSA public key could be taken by a third party or even be falsified.

We have not received any incident reports regarding this vulnerability so far and users can rest assured if firmware on the impacted products is being resolved

Where the RSA key pair had been created by the Cryptographic library with this vulnerability, additional steps are required after the firmware update. Depending on the affected, refer to Steps to check the key and measure to be taken described below to take a correct action.

In addition, do not connect the products directly to the internet, but use firewall, wire connected environment or securely protected private network environment if using Wi-Fi router. Set a private IP address as well.

For details, please refer to Securing products when connecting to a network.

Regarding vulnerability measure against buffer overflow for Laser Printers and Small Office Multifunction Printers – 10 March 2022

Multiple cases of buffer overflow vulnerabilities have been identified with Canon Laser Printers and Small Office Multifunctional Printers. Related CVEs are: CVE-2022-24672, CVE-2022-24673 and CVE-2022-24674. A list of affected models is given below.

Whilst we have not received any reports of exploitation, please upgrade the device firmware to the latest version.

This vulnerability suggests the possibility that if a product is connected directly to the Internet without using a wired or Wi-Fi router, a third party on the Internet may execute arbitrary code or the product could be subjected to Denial-of Service (DoS) attack.

We do not recommend connecting directly to the Internet – please use a private IP address on a secure private network configured via a firewall or wired/WiFi router. Please see for ‘security for product connected to a network.’

We will continue to work to further strengthen security measures to ensure that you can continue using Canon products with peace of mind. If vulnerabilities are identified in other products, we will immediately update this article.

Cross-site scripting vulnerability for laser printers and multifunction devices for small offices – 11 January 2022

A cross-site scripting vulnerability has been identified in the Remote UI function of Canon laser printers and multifunction devices for small office – see the affected models below (vulnerability identification number: JVN # 64806328).

For this vulnerability to be exploited, it is necessary for the attacker to be in the administrator mode. Whilst there have been no reports of data loss, we advise installing the latest firmware to enhance security. Updates can be found at

We also recommend that a private IP address is set and a network environment ensuring that connection is established through a firewall or Wi-Fi router that can restrict network access. Please see for more details of security measures when connecting devices to a network.

Affected products:


MF269dw, MF267dw, MF264dw
MF249dw, MF247dw, MF244dw, MF237w, MF232w

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

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.
