CVE-2021-27085

Estado: AnalizadaAlta (8.8)⚠ Explotación activa

Internet Explorer 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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector AV:N/UI:R indica explotación remota con interacción del usuario (T1203). RCE en IE permite ejecución de código arbitrario; impactos incluyen comandos, manipulación de datos y potencial cifrado (ransomware sugerido en KEV).

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.
