CVE-2016-1582

Estado: ModificadaMedia (5.5)—

LXD en versiones anteriores a 2.0.2 no establece adecuadamente los permisos cuando se cambia un recipiente sin privelegios a modo privilegiado, lo que permite a usuarios locales acceder a la lectura de todas las rutas arbitrarios en el directorio del contenedor a través de vectores no especificados.

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).
