CVE-2025-21344

Estado: AnalizadaAlta (7.8)—

Microsoft SharePoint Server 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.

Vector CVSS con UI:R indica explotación en cliente (T1203). SharePoint requiere interacción del usuario (abrir documento/archivo). RCE implica ejecución de código (T1059), acceso a datos (T1005) y potencial manipulación (T1565).

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.
