EPSON Status Monitor 3 version 8.0 contains an unquoted service path vulnerability that allows local attackers to potentially execute arbitrary code by exploiting the service binary path. Attackers can leverage the unquoted path in 'C:\Program Files\Common Files\EPSON\EPW!3SSRP\ES60RPB.EXE' to inject malicious executables and escalate privileges.

Versions of Epson AirPrint released prior to January 19, 2018 contain a reflective cross-site scripting (XSS) vulnerability, which can allow untrusted users on the network to hijack a session cookie or perform other reflected XSS attacks on a currently logged-on user.

Cross-site scripting (XSS) vulnerability in EPSON TMNet WebConfig 1.00 allows remote attackers to inject arbitrary web script or HTML via the WAD1 parameter to Forms/oadmin1.

The Epson Stylus SX510W embedded web management service fails to properly handle consecutive ampersand characters in query parameters when accessing /PRESENTATION/HTML/TOP/INDEX.HTML. A remote attacker can send a malformed request that triggers improper input parsing or memory handling, resulting in the printer process shutting down or powering off, causing a denial of service condition.

ESC/POS, a printer control language designed by Seiko Epson Corporation, lacks mechanisms for user authentication and command authorization, does not provide controls to restrict sources or destinations of network communication, and transmits commands without encryption or integrity protection.

Epson USB Display 1.6.0.0 contains an unquoted service path vulnerability in the EMPUDSA service running with LocalSystem privileges. Attackers can exploit the unquoted path by placing malicious executables in intermediate directories to gain elevated system access.

The com.epson.InstallNavi.helper tool, deployed with the EPSON printer driver installer, contains a local privilege escalation vulnerability due to multiple flaws in its implementation. It fails to properly authenticate clients over the XPC protocol and does not correctly enforce macOS’s authorization model, exposing privileged functionality to untrusted users. Although it invokes the AuthorizationCopyRights API, it does so using overly permissive custom rights that it registers in the system’s authorization database (/var/db/auth.db).

These rights can be requested and granted by the authorization daemon to any local user, regardless of privilege level. As a result, an attacker can exploit the vulnerable service to perform privileged operations such as executing arbitrary commands or installing system components without requiring administrative credentials.

EPSON EasyMP Network Projection 2.81 contains an unquoted service path vulnerability in the EMPNSWLSV service that allows local users to potentially execute arbitrary code. Attackers can exploit the unquoted path in C:\Program Files (x86)\EPSON Projector\EasyMP Network Projection V2\ to inject malicious code that would execute with LocalSystem privileges.

EPSON 1.124 contains an unquoted service path vulnerability in the SENADB service that allows local attackers to execute code with elevated system privileges. Attackers can exploit the unquoted path in C:\Program Files (x86)\EPSONP2B\Printer Software\Status Monitor\ to inject malicious executables that will run with LocalSystem permissions.

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. By default, the device comes (and functions) without a password. The user is at no point prompted to set up a password on the device (leaving a number of devices without a password). In this case, anyone connecting to the web admin panel is capable of becoming admin without using any credentials.

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. POST requests don't require (anti-)CSRF tokens or other mechanisms for validating that the request is from a legitimate source. In addition, CSRF attacks can be used to send text directly to the RAW printer interface. For example, an attack could deliver a worrisome printout to an end user.

The WebConfig functionality of Epson TM-C3500 and TM-C7500 devices with firmware version WAM31500 allows authentication bypass.

The Seiko Epson printer driver installers for LP-S9000 before 4.1.11 and LP-S7100 before 4.1.7, or as downloaded from the vendor between May 2010 and 20101125, set weak permissions for the "C:\Program Files" folder, which might allow local users to bypass intended access restrictions and create or modify arbitrary files and directories.

EPSON Network Utility 4.10 uses weak permissions (Everyone: Full Control) for eEBSVC.exe, which allows local users to gain privileges via a Trojan horse file.

The Epson "EasyMP" software is designed to remotely stream a users computer to supporting projectors.These devices are authenticated using a unique 4-digit code, displayed on-screen - ensuring only those who can view it are streaming.In addition to the password, each projector has a hardcoded "backdoor" code (2270), which authenticates to all devices.
