![]() ![]() ![]() Spring4Shell ( CVE-2022-22965), a remote code execution in Spring Framework via Data Binding on Java Development Kit (JDK) version 9 or later Ricoh is aware of these vulnerabilities disclosed by VMware:ĬVE-2022-22963, a remote code execution in Spring Cloud Function by malicious Spring Expression Ricoh is quickly working on updated firmware for each model, and more information will be provided as soon as it is made available. Ricoh encourages all customers who use the RICOH M C240FW and RICOH P C200W to visit this webpage and follow the workaround steps outlined for each model to ensure security.įor customers who use the RICOH M C550SRF, please disable the Web-Services service on the printer (TCP port 65002), which blocks the ability to exploit this vulnerability, by performing the following steps: Go to “Settings” > ”Network/Ports” > “TCP/IP” > “TCP/IP Port Access” and uncheck "TCP 65002 (WSD Print Service)” and save. Ricoh has already taken steps to address the vulnerability of impacted devices, listed here. Ricoh is aware of CVE-2023-23560, a Server-Side Request Forgery (SSRF) vulnerability that could potentially be leveraged by an attacker to remotely execute arbitrary code on an affected device. RICOH P C200W: For the RICOH M C550SRF, please contact Ricoh at 1-80, option 3 or 4, to schedule a service appointment to install the latest firmware to your device.Ī Server-Side Request Forgery (SSRF) vulnerability exists in some Ricoh devices. The updated firmware supersedes any previously recommended workarounds and addresses all vulnerabilities.įor the RICOH M C240FW and RICOH P C200W, please visit the following links to download the latest firmware and follow the steps to install. Resolution: Ricoh has issued updated firmware for the affected models to ensure security. Can only be exploited on a device that has already been compromised by other means.ĬVE-2023-26068 – Embedded Web Server: An embedded web server input sanitization vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26069 – Web API: A web API input validation vulnerability that can be leveraged to remotely execute arbitrary code. 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.ĬVE-2023-23560 – Server-Side Request Forgery: Vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26063 – Postscript Buffer Overflow: A type confusion vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26064 – Postscript Buffer Overflow: An out of bounds write vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26065 – Postscript Buffer Overflow: An integer overflow vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26066 – Postscript Buffer Overflow: An improper stack validation vulnerability that can be leveraged to remotely execute arbitrary code.ĬVE-2023-26067 – Input Validation: An input validation vulnerability that can be leveraged on an already compromised device to escalate privileges. Ricoh has already taken steps to address the vulnerabilities for the affected devices listed here. Ricoh is aware of the following vulnerabilities affecting the RICOH M C240FW, RICOH P C200W, and RICOH M C550SRF that could potentially be leveraged by an attacker to remotely execute arbitrary code or escalate privileges on a device already compromised by an attacker. Ricoh uses a Trusted Boot procedure that employs two methods to verify the validity of programs/firmware:Ī Ricoh device will not boot up unless its programs/firmware are verified to be authentic and safe for users.Several CVEs listed below have been issued affecting the identified devices. A root encryption key and cryptographic functions are also contained within the TPM and cannot be altered from the outside. The public key used for this verification is stored in an overwriteprotected, non-volatile region of the Ricoh Trusted Platform Module (TPM). Ricoh MFPs and printers use a digital signature to judge firmware validity. Ricoh’s TPM is a hardware security module that validates the controller core programs, Operating System, BIOS, boot loader and application firmware. Ricoh-designed devices are built using a Ricoh-only Trusted Platform Module (TPM) and are designed to not boot up if the firmware has been compromised. If a MFP or printer’s built-in software - also known as firmware - is altered or compromised, that device can then be used as a method of intrusion into the corporate network, as a means to damage the device or as a platform for other malicious purposes. ![]()
