Description

OpenStack Compute (nova) launches and schedules large networks of virtual
machines, creating a redundant and scalable cloud computing platform.
Compute provides the software, control panels, and APIs required to
orchestrate a cloud, including running virtual machine instances and
controlling access through users and projects.

It was discovered that the OpenStack Compute (nova) console websocket did
not correctly verify the origin header. An attacker could use this flaw to
conduct a cross-site websocket hijack attack. Note that only Compute setups
with VNC or SPICE enabled were affected by this flaw. (CVE-2015-0259)
