Vulnerability in Driver/Software Installation via Web Installer for Mac
Thank you for using Epson products.
July 7, 2025 Seiko Epson Corporation Epson Sales Corporation
A vulnerability has been confirmed in the Mac version of Epson Web Installer via Setup Navi (when installing using the Driver & Utility Combo Package Installer) on June 20th, 2025. This is a tool that allows you to install the latest drivers and related software on Mac computers all at once for some Epson products.
DESCRIPTION When the Mac version of Epson Web Installer is launched (via Drivers and Utilities Combo Package Installer or epson.sn), a privileged helper tool is registered and started. While this helper tool is running, it is possible for an application with arbitrary user privileges to connect to the tool and execute privileged operations (such as running commands, scripts, or installing packages) without administrator authentication.
IMPACT There have not been any reports of attacks exploiting this vulnerability.
This vulnerability affects the Drivers and Utilities Combo Package Installer and installation operations via epson.sn (Setup Navi) across a number of Epson products in the Inkjet, Laser, Large Format, Scanner, Commercial Photo and Print Systems.:
SUPPORTED OPERATING SYSTEMS macOS Sequoia(Mac OS 15.x) / macOS Sonoma(Mac OS 14.x) / macOS Ventura(Mac OS 13.x) / macOS Monterey(Mac OS 12.x) / macOS Big Sur(Mac OS 11.x) / macOS Catalina(Mac OS 10.15) / macOS Mojave(Mac OS 10.14) / macOS High Sierra(Mac OS 10.13) / macOS Sierra(Mac OS 10.12) / OS X El Capitan(Mac OS 10.11)
SOLUTION A patched version of Epson Web Installer was released and readily available on June 23, 2025 at 12:00 PM.
