A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.

The bug was discovered 06/20/2017. The weakness was shared 07/26/2018 with Red Hat (Website). The advisory is shared for download at access.redhat.com. This vulnerability is handled as CVE-2017-2637 since 11/30/2016. The attack may be launched remotely. No form of authentication is required for exploitation.
