CVE-2025-59251

Estado: ModificadaAlta (7.6)—

Microsoft Edge (Chromium-based) 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 interacción del usuario; RCE en navegador (Edge Chromium) se logra mediante explotación en cliente. CWE-94 sugiere ejecución de código. T1068 como impacto secundario porque CVSS:3.1 muestra C:H/I:H (compromiso e integridad) potencialmente con elevación de privilegios.

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.
