Estado: AnalizadaAlta (7.3)⚠ Explotación activa

Microsoft Publisher Security Feature Bypass Vulnerability

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).

CISA KEV — explotada activamente

🎯 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/UI:R (local, requiere privilegios limitados e interacción) indica escalada desde usuario local. CWE-693 sugiere fallo de control de seguridad que permite ejecución de código con mayores privilegios (T1068). La explotación de Publisher activaría comandos y acceso a datos.

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.
