CVE-2026-69764

Estado: AnalizadaAlta (8.8)—

Heap-based buffer overflow in Microsoft Office Word allows an unauthorized attacker to execute code over a network.

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.

Buffer overflow en Word con UI:R (requiere interacción del usuario al abrir un documento preparado). Vector CVSS red (AV:N) + interacción = T1203. Ejecución de código no especificada → T1059 padre.

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.
