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.

The ability to specify a desired role when connecting to OpenSSH is a feature of how OpenSSH interacts with SELinux.  Users can only assign themselves SELinux roles which they have permission to access.  They cannot assign themselves arbitrary roles.",
