Descriptions

The NFS service in EMC Isilon OneFS 8.1.0.0, 8.0.1.0 - 8.0.1.1, and 8.0.0.0 - 8.0.0.4 maintains default NFS export settings (including the NFS export security flavor for authentication) that can be leveraged by current and future NFS exports. This NFS service contained a flaw that did not properly propagate changes made to the default security flavor to all new and existing NFS exports that are configured to use default NFS export settings and that are mounted after those changes are made. This flaw may potentially allow NFS clients to access affected NFS exports using the default and potentially weaker security flavor even if a more secure one was selected to be used by the OneFS administrator, aka an "NFS Export Security Setting Fallback Vulnerability."

El servicio NFS en EMC Isilon OneFS 8.1.0.0, 8.0.1.0 - 8.0.1.1 y 8.0.0.0 - 8.0.0.4 mantiene las opciones de exportación NFS por defecto (incluyendo la parte especifica de seguridad del "NFS export" para autenticación) que puede aprovecharse para exportaciones NFS actuales y futuras. El servicio NFS contenía un error que no propagaba correctamente los cambios realizados en la parte específica de seguridad para todas las exportaciones NFS nuevas y existentes que están configuradas para emplear opciones de exportación NFS por defecto y están montadas una vez se han realizado esos cambios. Este error podría permitir que clientes NFS accedan a exportaciones NFS afectadas empleando la parte específica de seguridad por defecto y, potencialmente, más débil, incluso aunque se haya seleccionado una más segura para ser empleada por el administrador OneFS. Esto también se conoce como "NFS Export Security Setting Fallback Vulnerability".
