CVE-2020-16017

Estado: AnalizadaCrítica (9.6)⚠ Explotación activa

Un uso de la memoria previamente liberada en site isolation en Google Chrome versiones anteriores a 86.0.4240.198, permitió a un atacante remoto que había comprometido el proceso del renderizador llevar a cabo potencialmente un escape del sandbox por medio de una página HTML diseñada

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.

Requiere interacción del usuario (UI:R) con página HTML crafted. CWE-416 (use-after-free) en site isolation permite escape de sandbox tras comprometer renderer, logrando ejecución arbitraria y posible escalada.

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.
