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.
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.
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:

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.
After investigation into the ‘Ripple20’ vulnerability, there has been no identified issue with Canon printer products.
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.
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.
Eleven vulnerabilities, dubbed “URGENT/11” (CVE-2019-12255 through to CVE-2019-12265), have been identified within the VxWorks operating system. It has transpired that the IPnet TCP/IP stack used in the VxWorks operating system has also been used in other real-time operating systems, opening up the possibility for vulnerabilities (CVE-2019-12255, CVE-2019-12262 and CVE-2019-12264) to exist in a broader range of products.
A number of legacy European models may be vulnerable to this issue as they have been identified as using the affected IPnet TCP/IP stack:
Thank you very much for using Canon products.
An international team of security researchers has drawn our attention to a vulnerability related to communications via the Picture Transfer Protocol (PTP), which is used by Canon digital cameras, as well as a vulnerability related to firmware updates.

Recently, researchers reported on vulnerabilities found in the communication protocols in the fax functions of certain products. (CVE-ID: CVE-2018-5924, CVE 2018-5925). For information regarding the impact of these vulnerabilities on Canon products equipped with fax functions, please see below:
Based on our review, as they do not employ the colour G3 Fax Protocol exploited by these vulnerabilities, the following products are unaffected: imageRUNNER/iR, imageRUNNER ADVANCE, LASER CLASS, imagePRESS, FAXPHONE, GP and imageCLASS/i-SENSYS series models equipped with fax functions.
MAXIFY and PIXMA series products equipped with fax functions do make use of the Colour G3 Fax Protocol. However, we have not identified any risk of malicious code being executed via the fax circuit or risk to the security of information saved on these devices.
We will continue to monitor this situation and take appropriate action necessary to help ensure the security of our devices.

All Canon laser multifunction printers and Canon laser printers and their related software products, except the above-mentioned, are not affected by these vulnerabilities through any known exploitation process. Customers can continue using our products reliably.
Canon is constantly working to ensure the highest level of security is reached in all our products and solutions. We take the security of our customer information seriously and its protection is our utmost priority.
Recently, a researcher made public a vulnerability known as KRACKs in the standard wireless LAN (Wi-Fi) encryption protocol WPA2. This vulnerability allows an attacker to intentionally intercept the wireless transmission between the client (terminal equipped with Wi-Fi functionality) and the access point (the router etc.) to perform potentially malicious activity. For that reason, this vulnerability cannot be exploited by anyone outside the range of the Wi-Fi signal or by anyone in a remote location using the internet as an intermediary.
We have yet to confirm that any issues have been encountered by users of Canon products as a result of this vulnerability, however, in order to allow customers to continue using our products with peace of mind, we recommend the following preventative measures:
•Use a USB cable or Ethernet cable to directly connect compatible devices to a network
•Encrypt data transmission from devices that enable encryption settings (TLS/IPSec)
•Use such physical media as SD cards with compatible devices
•Use such settings as Wireless Direct and Direct Connect with compatible devices
As the operation procedures and functions offered vary from device to device, please consult your device’s manual for more details. We also recommend you take appropriate measures for such devices as your PC or smartphone. For information on the appropriate measures for each device, please contact the device’s manufacturer.
