9.9 · CRITICALOverview
CVE-2017-2637 is a critical-severity vulnerability affecting redhat openstack. It was published on July 26, 2018 and has a CVSS 3.0 base score of 9.9 (CRITICAL).
This vulnerability has a CVSS 3.0 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from redhat. Update openstack 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.
