A resource-permission flaw was found in the openstack-tripleo-heat-templates package where ceph.client.openstack.keyring is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume.
Se detectó una vulnerabilidad de permisos de recursos en el paquete openstack-tripleo-heat-templates donde se crea ceph.client.openstack.keyring con el permiso world-readable. Un atacante local con acceso a la clave podría leer o modificar datos en los pools de memoria del clúster de Cepth para OpenStack como si el atacante fuera el servicio OpenStack, pudiendo leer o modificar datos en un volumen de OpenStack Block Storage.

To exploit this flaw, the attacker must have local access to an overcloud node. However by default, access to overcloud nodes is restricted and accessible only from the management undercloud server on an internal network. Follow good security principles in your networking environment to ensure that network access is properly controlled.
