tmpfiles.d/systemd.conf en systemd en versiones anteriores a 229 utiliza permisos débiles para /var/log/journal/%m/system.journal, lo que permite a usuarios locales obtener información sensible leyendo el archivo.

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).
