Printers and Multifunction Printers (MFPs) provided by Ricoh Company, Ltd. do not implement restrictions on SSH port forwarding, allowing to connect to arbitrary destinations. When SSH is enabled on an affected product, SSH port forwarding may be leveraged to connect to other node on the LAN.

Multiple laser printers and MFPs (multifunction printers) which implement Ricoh Web Image Monitor contain a reflected cross-site scripting vulnerability. An arbitrary script may be executed on the web browser of the user who accesses a crafted URL.

Multiple printer drivers provided by Ricoh Company, Ltd. and KONICA MINOLTA JAPAN, INC. contain a privilege escalation vulnerability. If this vulnerability is exploited, an attacker who can log in to a computer running an affected printer driver could elevate privileges by using a specially crafted driver.

Open redirect vulnerability exists in Multiple laser printers and MFPs which implement Ricoh Web Image Monitor. When accessing a specially crafted URL, the user may be redirected to an arbitrary website. As a result, the user may become a victim of a phishing attack.

The installer for ジョブログ集計/分析ソフトウェア RICOHジョブログ集計ツール versions prior to Ver.1.3.7 contains an issue with the DLL search path, which may lead to insecurely loading Dynamic Link Libraries. As a result, arbitrary code may be executed with administrative privileges.

RICOH Web Image Monitor 1.09 contains an HTML injection vulnerability in the address configuration CGI script that allows attackers to inject malicious HTML code. Attackers can exploit the entryNameIn and entryDisplayNameIn parameters to insert arbitrary HTML content, potentially enabling cross-site scripting attacks.

Improper authorization vulnerability exists in RICOH Streamline NX 3.5.1 to 24R3. If a man-in-the-middle attack is conducted on the communication between the affected product and its user, and some crafted request is processed by the product, the user's registration information and/or OIDC (OpenID Connect) tokens may be retrieved.

RICOH Streamline NX versions 3.5.1 to 24R3 are vulnerable to tampering with operation history. If an attacker can perform a man-in-the-middle attack, they may alter the values of HTTP requests, which could result in tampering with the operation history of the product’s management tool.

A reflected cross-site scripting vulnerability via a specific parameter exists in SLNX Help Documentation of RICOH Streamline NX. If this vulnerability is exploited, an arbitrary script may be executed in the web browser of the user who accessed the product.

An unauthenticated attacker who can connect to TCP port 9100 can issue a Printer Job Language (PJL) command that will crash the target device. The device will reboot, after which the attacker can reissue the command to repeatedly crash the device. A malformed PJL variable FORMLINES is set to a non number value causing the target to crash.

An unauthenticated attacker may perform a limited server side request forgery (SSRF), forcing the target device to open a TCP connection to an arbitrary port number on an arbitrary IP address. This SSRF leverages the WS-Addressing ReplyTo element in a Web service (HTTP TCP port 80) SOAP request. The attacker can not control the data sent in the SSRF connection, nor can the attacker receive any data back. This SSRF is suitable for TCP port scanning of an internal network when the Web service (HTTP TCP port 80) is exposed across a network segment.

An unauthenticated attacker who can access either the HTTP service (TCP port 80), the HTTPS service (TCP port 443), or the IPP service (TCP port 631), can leak several pieces of sensitive information from a vulnerable device. The URI path /etc/mntinfo.csv can be accessed via a GET request and no authentication is required. The returned result is a comma separated value (CSV) table of information. The leaked information includes the device’s model, firmware version, IP address, and serial number.

RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.7.0 contains an issue with use of less trusted source, which may allow an attacker who can conduct a man-in-the-middle attack to eavesdrop upgrade requests and execute a malicious DLL with custom code.

Path traversal vulnerability exists in RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.242.0. If this vulnerability is exploited, arbitrary code may be executed on the PC where the product is running by tampering with specific files used on the product.

External control of file name or path issue exists in RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.242.0. If an attacker sends a specially crafted request, arbitrary files in the file system can be overwritten with log data.

Reflected cross-site scripting vulnerability exists in the laser printers and MFPs (multifunction printers) which implement Ricoh Web Image Monitor. If exploited, an arbitrary script may be executed on the web browser of the user who accessed Web Image Monitor. As for the details of affected product names and versions, refer to the information provided by the vendors under [References].

Stack-based buffer overflow vulnerability exists in multiple laser printers and MFPs which implement Ricoh Web Image Monitor. If this vulnerability is exploited, receiving a specially crafted request created and sent by an attacker may lead to arbitrary code execution and/or a denial-of-service (DoS) condition. As for the details of affected product names and versions, refer to the information provided by the vendors under [References].

Use of potentially dangerous function issue exists in Ricoh Streamline NX PC Client. If this vulnerability is exploited, files in the PC where the product is installed may be altered.

Use of potentially dangerous function issue exists in Ricoh Streamline NX PC Client. If this vulnerability is exploited, an attacker may create an arbitrary file in the PC where the product is installed.

Use of hard-coded credentials issue exists in Ricoh Streamline NX PC Client ver.3.7.2 and earlier. If this vulnerability is exploited, an attacker may obtain LocalSystem Account of the PC where the product is installed. As a result, unintended operations may be performed on the PC.

Improper restriction of communication channel to intended endpoints issue exists in Ricoh Streamline NX PC Client ver.3.6.x and earlier. If this vulnerability is exploited, arbitrary code may be executed on the PC where the product is installed.

The driver installation package created by Printer Driver Packager NX v1.0.02 to v1.1.25 fails to detect its modification and may spawn an unexpected process with the administrative privilege. If a non-administrative user modifies the driver installation package and runs it on the target PC, an arbitrary program may be executed with the administrative privilege.

Ricoh mpc4504ex devices with firmware 1.06 mishandle credentials.

Cross-site scripting vulnerability in Aficio SP 4210N firmware versions prior to Web Support 1.05 allows a remote authenticated attacker with an administrative privilege to inject an arbitrary script.

Untrusted search path vulnerability in the installer of Device Software Manager prior to Ver.2.20.3.0 allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.

RICOH Printer series SP products 320DN, SP 325DNw, SP 320SN, SP 320SFN, SP 325SNw, SP 325SFNw, SP 330SN, Aficio SP 3500SF, SP 221S, SP 220SNw, SP 221SNw, SP 221SF, SP 220SFNw, SP 221SFNw v1.06 were discovered to contain a stack buffer overflow in the file /etc/wpasupplicant.conf. This vulnerability allows attackers to cause a Denial of Service (DoS) via crafted overflow data.

An issue was discovered in RICOH Streamline NX Client Tool and RICOH Streamline NX PC Client that allows attackers to escalate local privileges.

Ricoh SP C250DN 1.05 devices have an Authentication Method Vulnerable to Brute Force Attacks. Some Ricoh printers did not implement account lockout. Therefore, it was possible to obtain the local account credentials by brute force.

Ricoh SP C250DN 1.05 devices allow denial of service (issue 1 of 3). Some Ricoh printers were affected by a wrong LPD service implementation that lead to a denial of service vulnerability.

Ricoh SP C250DN 1.05 devices have a fixed password. FTP service credential were found to be hardcoded within the printer firmware. This would allow to an attacker to access and read information stored on the shared FTP folders.
