CVE-2024-49029

Estado: AnalizadaAlta (7.8)—

Microsoft Excel Remote Code Execution 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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L + UI:R indica explotación en cliente (T1203): abrir fichero Excel preparado. Código remoto (RCE) en Excel permite ejecución de comandos (T1059), lectura de datos sensibles y manipulación de contenido.

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.
