CVE-2025-47181

Estado: AnalizadaAlta (8.8)—

Improper link resolution before file access ('link following') in Microsoft Edge (Chromium-based) allows an authorized attacker to elevate privileges locally.

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 AV:L (acceso local) sin UI:R y con PR:L (usuario con privilegios limitados) permite escalada de privilegios mediante resolución impropia de enlaces (CWE-59 link following), confirmado por descripción explícita de 'elevate privileges locally'.

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.
