CVE-2018-4237
Se ha descubierto un problema en algunos productos Apple. Las versiones de iOS anteriores a la 11.4, las versiones de macOS anteriores a la 10.13.5, las versiones de tvOS anteriores a la 11.4 y las versiones de watchOS anteriores a la 4.3.1 se han visto afectadas. El problema implica el componente "libxpc". Permite que los atacantes obtengan privilegios mediante una app manipulada que aprovecha un error de lógica.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 14%
- Percentil entre todas las CVEs puntuadas: 96
- Fecha de la puntuación: 9/10/2026
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.
