FKIE_CVE-2025-10541

Vulnerability from fkie_nvd - Published: 2025-09-25 15:16 - Updated: 2026-10-01 16:10
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
iMonitor EAM 9.6394 installs a system service (eamusbsrv64.exe) that runs with NT AUTHORITY\SYSTEM privileges. This service includes an insecure update mechanism that automatically loads files placed in the C:\sysupdate\ directory during startup. Because any local user can create and write to this directory, an attacker can place malicious DLLs or executables in it. Upon service restart, the files are moved to the application’s installation path and executed with SYSTEM privileges, leading to privilege escalation.

Este servicio incluye un mecanismo de actualizaci\u00f3n inseguro que carga autom\u00e1ticamente archivos ubicados en el directorio C:\\sysupdate\\ durante el inicio. Debido a que cualquier usuario local puede crear y escribir en este directorio, un atacante puede colocar DLLs o ejecutables maliciosos en \u00e9l. Al reiniciar el servicio, los archivos se mueven a la ruta de instalaci\u00f3n de la aplicaci\u00f3n y se ejecutan con privilegios de SYSTEM, lo que lleva a una escalada de privilegios."
