CVE-2021-47825

Estado: AplazadaAlta (8.5)—

Acer Updater Service 1.2.3500.0 contains an unquoted service path vulnerability that allows local users to execute code with elevated system privileges. Attackers can exploit the unquoted path in C:\Program Files\Acer\Acer Updater\ to inject malicious executables that will run 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.

AV:L + PR:L sin UI:R = escalada local sin interacción (T1068). El servicio con permisos LocalSystem permite ejecutar código arbitrario (T1059) con privilegios elevados (T1548).

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.
