Estado: AnalizadaAlta (7.1)—

Improper access control in Office for Android allows an unauthorized attacker to perform spoofing locally.

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/UI:R indica explotación en cliente (T1203). CWE-284 de control de acceso permite suplantación de identidad (spoofing), mapeado a T1036 (camuflaje/falsificación) como impacto principal en aplicaciones Office.

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.
