CVE-2021-47880

Estado: AplazadaAlta (8.5)—

Realtek Wireless LAN Utility 700.1631 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted service path by inserting malicious code in the system root path that would execute during application startup or system reboot.

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.

Vector AV:L/PR:L sin UI:R indica escalada local. CWE-428 (ruta sin comillas) permite inyectar código malicioso en la ruta del servicio que se ejecuta con privilegios elevados al reinicio o inicio de la aplicación.

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.
