CVE-2020-11012

Estado: ModificadaAlta (7.5)—

MinIO versiones anteriores a la versión RELEASE.2020-04-23T00-58-49Z, tiene un problema de omisión de autenticación en la API de administración de MinIO. Dada una clave de acceso de administrador, es posible llevar a cabo operaciones de la API del administrador, es decir, crear nuevas cuentas de servicio para claves de acceso existentes, sin conocer la clave secreta del administrador. Esto se ha corregido y publicado en la versión RELEASE.2020-04-23T00-58-49Z.
