CVE-2021-37976

Estado: AnalizadaMedia (6.5)⚠ Explotación activa

Una implementación inapropiada en Memory en Google Chrome versiones anteriores a 94.0.4606.71, permitía a un atacante remoto conseguir información potencialmente confidencial de la memoria del proceso 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 maliciosa para leer memoria del proceso Chrome. CWE-862 (falta de autorización) + acceso a datos sensibles.

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.
