As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

An authenticated attacker can reconfigure the target device to use an external service (such as LDAP or FTP) controlled by the attacker. If an existing password is present for an external service, the attacker can force the target device to authenticate to an attacker controlled device using the existing credentials for that external service. In the case of an external LDAP or FTP service, this will disclose the plaintext password for that external service to the attacker.

An unauthenticated attacker who can connect to the Web Services feature (HTTP TCP port 80) can issue a WS-Scan SOAP request containing an unexpected JobToken value which will crash the target device. The device will reboot, after which the attacker can reissue the command to repeatedly crash the device.

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 blind server side request forgery (SSRF), due to a CLRF injection issue that can be leveraged to perform HTTP request smuggling. This SSRF leverages the WS-Addressing feature used during a WS-Eventing subscription SOAP operation. The attacker can control all the HTTP data sent in the SSRF connection, but the attacker can not receive any data back from this connection.

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 authenticated attacker may trigger a stack based buffer overflow by performing a malformed request to either the HTTP service (TCP port 80), the HTTPS service (TCP port 443), or the IPP service (TCP port 631). The malformed request will contain an empty Origin header value and a malformed Referer header value. The Referer header value will trigger a stack based buffer overflow when the host value in the Referer header is processed and is greater than 64 bytes in length.

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/mnt_info.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.

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].

Initialization of a resource with an insecure default vulnerability exists in JavaTM Platform Ver.12.89 and earlier. If this vulnerability is exploited, the product may be affected by some known TLS1.0 and TLS1.1 vulnerabilities. As for the specific products/models/versions of MFPs and printers that contain JavaTM Platform, see the information provided by the vendor.

Out-of-bounds write vulnerability exists in Ricoh MFPs and printers. If a remote attacker sends a specially crafted request to the affected products, the products may be able to cause a denial-of-service (DoS) condition and/or user's data may be destroyed.

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.

Cross-site request forgery vulnerability in multiple printers and scanners which implement Web Based Management provided by BROTHER INDUSTRIES, LTD. allows a remote unauthenticated attacker to perform unintended operations on the affected product.
