Ricoh understands the importance of security and is committed to managing its products and services with the most advanced security technologies possible for customers around the world.

Ricoh is aware of these vulnerabilities disclosed by VMware:

• CVE-2022-22963, a remote code execution in Spring Cloud Function by malicious Spring Expression

• Spring4Shell (CVE-2022-22965), a remote code execution in Spring Framework via Data Binding on Java Development Kit (JDK) version 9 or later

We are working with our security experts to address this as a high-priority issue and are now investigating which products or services may be affected. We will publish an advisory for the affected models. As of April 6, 2022, we have confirmed that these vulnerabilities do not affect the following main Ricoh products and services:

• Ricoh Smart Integration (RSI) Platform and its applications

• RICOH Streamline NX V2, V3

• Multifunction Printers

As more information becomes available, we will update this web page.

When using products impacted by this security issue, Ricoh strongly advises that customers use SSID (Service Set Identifier) and a password, and avoid using a WPS (Wi-Fi® Protected Setup) connection when establishing a wireless connection. Please refer to the following steps:

Ricoh is aware of the security vulnerability, commonly called "Print Nightmare," registered as CVE-2021-34527 and published by Microsoft on July 1, 2021.

The vulnerability allows remote code execution by a standard Microsoft Active Domain user by exploiting vulnerabilities in the print spooler process used by all Microsoft operating systems. Ricoh print drivers are not directly affected by this vulnerability, however, because print drivers for Microsoft Windows operating systems make use of the printer spooler process, any potential mitigation might affect the ability to print or otherwise properly use print drivers.

The security and integrity of our customer's data and devices is of the utmost importance to Ricoh. In the light of Microsoft releasing security updates as of July 6, we advise our customers to refer to the Microsoft advisory page.

Please note that a closely related vulnerability (registered under CVE-2021-1675) has been patched by Microsoft recently.

Updates will be provided as more information becomes available.

Update: Notice on Ripple20 Treck TCP/IP Stack Potential Vulnerabilities

First published July 8, 2020

Date of current status July 31, 2020

Ricoh is aware of the security vulnerabilities known as the “Ripple20” disclosed by the JSOF on June 16, 2020. These vulnerabilities could potentially allow a remote hacker to trigger an information leak if a specific TCP/IP stack version is used.

https://www.jsof-tech.com/ripple20/

https://www.us-cert.gov/ics/advisories/icsa-20-168-01

We have confirmed that Ricoh A3-sized multi-function printers, production printers, digital duplicators, Interactive White Boards, projectors, and Unified Communication Systems do not use IP stack modules from Treck Inc. and Kasago of Zuken Elmic, Inc.

We also have confirmed that no current A4-sized device sold by Ricoh USA, Inc. is impacted with these potential vulnerabilities. Within the US, four devices were previously sold that could have been impacted:

• RICOH SP 1210N (discontinued 1/1/2014)

• RICOH GX e3300N (discontinued 4/4/2012)

The Potential Vulnerability Summary

The affected printer has potential vulnerabilities which may cause a device stall, memory destruction, and network failure, but won't be exploited by a springboard attack or cause confidential information leakage. Please visit here.

This vulnerability will not affect devices connected to the customer’s network if the network is properly configured against external attacks. Ricoh recommends always using best practices for network protection, including:

1. When the device is connected to a network, ensure that the network is protected, for example, by a firewall.
2. Install the device in a secure network where users restrictions are in place.

Resolution

Please download the updated firmware as below. Ricoh will release further updated firmware on the driver site as it is available.

The security and integrity of our customers' data and devices remain of utmost importance to Ricoh and will publish additional advisories for any other affected models, when applicable.

Ransomware continues to be a serious issue for businesses. It has recently come to our attention that a small number of Ricoh devices on a restricted testing network have been impacted. These devices contain no customer or confidential information, and are not on the main Ricoh network. We are working with law enforcement and other appropriate third-parties to conduct a forensic investigation.

We take these matters seriously and are committed to completing a full investigation. Should there be more information uncovered, we will update this page accordingly.
