CVE-2021-47823

Estado: AplazadaAlta (8.5)—

Acer ePowerSvc 6.0.3008.0 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted path in the service configuration to inject malicious code that would execute with LocalSystem permissions during service startup.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de ruta de servicio sin entrecomillado en ePowerSvc que permite a usuarios locales (PR:L) ejecutar código con permisos LocalSystem sin interacción del usuario (UI:N), clásico T1068 para escalada local. CWE-428 confirma el vector de inyección en ruta de servicio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
