CVE-2019-19363
An issue was discovered in Ricoh (including Savin and Lanier) Windows printer drivers prior to 2020 that allows attackers local privilege escalation. Affected drivers and versions are: PCL6 Driver for Universal Print - Version 4.0 or later PS Driver for Universal Print - Version 4.0 or later PC FAX Generic Driver - All versions Generic PCL5 Driver - All versions RPCS Driver - All versions PostScript3 Driver - All versions PCL6 (PCL XL) Driver - All versions RPCS Raster Driver - All version
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 4.44%
- Percentil entre todas las CVEs puntuadas: 91
- Fecha de la puntuación: 7/10/2026
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.
