Openstack Octavia Access Control Vulnerability

Description

An access-control flaw was found in the Octavia service when the cloud platform was deployed using Red Hat OpenStack Platform Director. An attacker could cause new amphorae to run based on any arbitrary image. This meant that a remote attacker could upload a new amphorae image and, if requested to spawn new amphorae, Octavia would then pick up the compromised image.

Mitigation

To prevent this vulnerability:

1. Update Octavia's configuration setting (octavia.conf) to amp_image_owner_id = $UUID_OF_SERVICE_PROJECT on all Octavia nodes.
2. Enable the new configuration by restarting both octavia_worker and octavia_health_manager.
