RESOLUTION

HPE has provided the following mitigations to resolve this issue:

  • Deploy rate-limiting proxies or web application firewalls

    • For all versions of Glance which expose either the v1 or the v2 /images API, operators are recommended to deploy external rate-limiting proxies or web application firewalls. This will provide a front-end layer of protection to Glance. The Glance database should be monitored for abnormal growth. Although rate-limiting does not eliminate this vulnerability, it will slow it to the point where operators can react prior to a Denial of Service occurring.

  • Restrict image creation to the admin role

    • Another possible mitigation is to restrict image creation to the admin role. This should only be done when there are Glance nodes dedicated to end-user access only.

    • For further recommendations on external rate limiting and restricting image creation, please refer to the Open Stack Security Notice OSSN-0076 -https://wiki.openstack.org/wiki/OSSN/OSSN-0076 Non-HPE site
