CVE-2022-24842

Estado: ModificadaAlta (8.8)—

MinIO es un almacenamiento de objetos de alto rendimiento publicado bajo la Licencia Pública General Affero versión v3.0 de GNU. Se ha encontrado un problema de seguridad en el que un usuario no administrador es capaz de crear cuentas de servicio para el usuario root u otros usuarios administradores y luego es capaz de asumir sus políticas de acceso por medio de las credenciales generadas. Esto, a su vez, permite al usuario escalar sus privilegios a los del usuario root. Esta vulnerabilidad ha sido resuelta en el pull request #14729 y es incluida en 'RELEASE.2022-04-12T06-55-35Z".

Leer descripción completaMostrar menos

Los usuarios que no puedan actualizar pueden mitigar este problema al añadir explícitamente una política de denegación "admin:CreateServiceAccount", pero esto, a su vez, deniega al usuario la capacidad de crear sus propias cuentas de servicio

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).
