Verification Bypass vulnerability exists in EPSON 150075647YWWV110 EasyMP Network Updater Ver.1.20. The Epson projector can be updated by encrypted firmware through USB.

Buffer Overflow vulnerability in EPSON L14150 FL27PB allows a remote attacker to execute arbitrary code via the RAW Printing Service (JetDirect) on TCP port 9100

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.

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.

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.

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.

EPSON WebConfig and Epson Web Control for SEIKO EPSON Projector Products do not restrict excessive authentication attempts. An administrative user's password may be identified through a brute force attack.

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.

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. With the SNMPv1 public community, all values can be read, and with the epson community, all the changeable values can be written/updated, as demonstrated by permanently disabling the network card or changing the DNS servers.

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.

Improper input validation vulnerability in SEIKO EPSON printer Web Config allows a remote attacker to turned off the printer. [Note] Web Config is the software that allows users to check the status and change the settings of SEIKO EPSON printers via a web browser. Web Config is pre-installed in some printers provided by SEIKO EPSON CORPORATION. For the details of the affected product names/model numbers, refer to the information provided by the vendor.

Cross-site scripting vulnerability in SEIKO EPSON printers/network interface Web Config allows a remote authenticated attacker with an administrative privilege to inject an arbitrary script. [Note] Web Config is the software that allows users to check the status and change the settings of SEIKO EPSON printers/network interface via a web browser. According to SEIKO EPSON CORPORATION, it is also called as Remote Manager in some products. Web Config is pre-installed in some printers/network interface provided by SEIKO EPSON CORPORATION. For the details of the affected product names/model numbers, refer to the information provided by the vendor.

Cross-site request forgery (CSRF) vulnerability in SEIKO EPSON printers/network interface Web Config allows a remote unauthenticated attacker to hijack the authentication and perform unintended operations by having a logged-in user view a malicious page. [Note] Web Config is the software that allows users to check the status and change the settings of SEIKO EPSON printers/network interface via a web browser. According to SEIKO EPSON CORPORATION, it is also called as Remote Manager in some products. Web Config is pre-installed in some printers/network interface provided by SEIKO EPSON CORPORATION. For the details of the affected product names/model numbers, refer to the information provided by the vendor.

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

In Epson iProjection v2.30, the driver file EMPMPAU.sys allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of not validating input values from IOCtl 0x9C402406 and IOCtl 0x9C40240A. (0x9C402402 has only a NULL pointer dereference.) This affects \Device\EMPMPAUIO and \DosDevices\EMPMPAU.

In Epson iProjection v2.30, the driver file (EMPNSAU.sys) allows local users to cause a denial of service (BSOD) via crafted input to the virtual audio device driver with IOCTL 0x9C402402, 0x9C402406, or 0x9C40240A. \Device\EMPNSAUIO and \DosDevices\EMPNSAU are similarly affected.

Untrusted search path vulnerability in self-extracting files created by EpsonNet SetupManager versions 2.2.14 and earlier, and Offirio SynergyWare PrintDirector versions 1.6x/1.6y and earlier allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.

Lack of an anti-CSRF token in the entire administrative interface in EPSON EPS TSE Server 8 (21.0.11) allows an unauthenticated attacker to force an administrator to execute external POST requests by visiting a malicious website.

A Cross-Site Scripting (XSS) issue in the 'update user' and 'delete user' functionalities in settings/users.php in EPSON EPS TSE Server 8 (21.0.11) allows an authenticated attacker to inject a JavaScript payload in the user management page that is executed by an administrator.

Unrestricted access to the log downloader functionality in EPSON EPS TSE Server 8 (21.0.11) allows an unauthenticated attacker to remotely retrieve administrative hashed credentials via the maintenance/troubleshoot.php?download=1 URI.

Untrusted search path vulnerability in the installers of multiple SEIKO EPSON products allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.
