The boot-from-volume feature in OpenStack Compute (Nova) Folsom and Essex, when using nova-volumes, allows remote authenticated users to boot from other users' volumes via a volume id in the block_device_mapping parameter.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0208 advisory.

    The openstack-nova packages provide OpenStack Compute (code name Nova), a     cloud computing fabric controller.

    The openstack-nova packages have been upgraded to upstream version     2012.2.2, which provides a number of bug fixes over the previous version.

    This update also fixes the following security issues:

    It was found that the boot-from-volume feature in nova-volume did not     correctly validate if the user attempting to boot an image was permitted     to do so. An authenticated user could use this flaw to bypass     intended restrictions, allowing them to boot images they would otherwise     not have access to, exposing data stored in other users' images. This     issue did not affect configurations using the Cinder block storage     mechanism, which is the default in Red Hat OpenStack. (CVE-2013-0208)

    When OpenStack Nova was configured to provide guest instances with libvirt     and said guests used LVM-backed ephemeral storage     (libvirt_images_type=lvm in /etc/nova/nova.conf), the contents of the     physical volume were not wiped before the volume was returned to the system     for use by a different guest instance. This could lead to a new instance     being able to access files and data from a previous instance. This issue     did not affect configurations using the Cinder block storage mechanism,     which is the default in Red Hat OpenStack. (CVE-2012-5625)

    Red Hat would like to thank the OpenStack project for reporting these     issues. Upstream acknowledges Phil Day as the original reporter of     CVE-2013-0208, and Eric Windisch as the original reporter of CVE-2012-5625.

    All users of openstack-nova are advised to upgrade to these updated     packages, which correct these issues. After installing the updated     packages, the Nova running services will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Phil Day discovered that nova-volume did not validate access to volumes. An authenticated attacker could exploit this to bypass intended access controls and boot from arbitrary volumes.
