Technical description
OpenStack PackStack 2012.2.1, when the Open vSwitch (OVS) monolithic plug-in is not used, does not properly set the libvirt_vif_driver configuration option when generating the nova.conf configuration, which causes the firewall to be disabled and allows remote attackers to bypass intended access restrictions.
Remediation
Check the references section for vendor advisories and patches from redhat. Update packstack to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
