CVE-2022-1096

Estado: AnalizadaAlta (8.8)⚠ Explotación activa💥 PoC

Una confusión de tipo en V8 en Google Chrome versiones anteriores a 99.0.4844.84, permitía a un atacante remoto explotar potencialmente la corrupción de la pila 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

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.

🎯 Técnicas ATT&CK

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

AV:N, UI:R, sin privilegios previos indica explotación mediante navegación (T1203). Corrupción de heap en V8 posibilita ejecución de código (T1059) y manipulación de datos (T1565.001) con alto riesgo (CVSS 8.8).

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.
