Vulnerabilidades de Epson

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 EMP_NSWLSV 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)\EPSON_P2B\Printer Software\Status Monitor\ to inject malicious executables that will run with LocalSystem permissions.
