CVE-2020-36929

Estado: AnalizadaAlta (8.5)—

Brother BRPrint Auditor 3.0.7 contains an unquoted service path vulnerability in its Windows service configurations that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted file paths in BrAuSvc and BRPA_Agent services to inject malicious executables and escalate privileges on the system.

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 de privilegios local. Rutas sin comillas en servicios Windows permiten inyectar ejecutables maliciosos (T1059) y elevar privilegios (T1548: Abuse Elevation Control Mechanism).

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.
