CVE-2017-13855

Estado: ModificadaMedia (5.5)—💥 Exploit

Se ha descubierto un problema en algunos productos Apple. Las versiones de iOS anteriores a la 11.2, las versiones de macOS anteriores a la 10.13.2, las versiones de tvOS anteriores a la 11.2 y las versiones de watchOS anteriores a la 4.2 se han visto afectadas. El problema afecta al componente "Kernel". Permite que los atacantes omitan las restricciones de lectura de memoria planeadas mediante una app manipulada, lo que da lugar a una confusión de tipos.

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).

💥 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.
