CVE-2019-0948
Estado: ModificadaMedia (4.7)—💥 Exploit
Existe una vulnerabilidad de revelación de información en el Windows Event Viewer ( eventvwr.msc) cuando analiza incorrectamente una entrada XML, conteniendo una referencia a una entidad exterior (conocido como Windows Event information Disclosure Vulnerability)
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N
- Puntuación base: 4.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 13%
- 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.
