CFME: CSRF protection vulnerability via permissive check of the referrer header

It was found that the CloudForms before 5.6.2.2, and 5.7.0.7 did not properly apply permissions controls to VM IDs passed by users. A remote, authenticated attacker could use this flaw to execute arbitrary VMs on systems managed by CloudForms if they know the ID of the VM.

The dialog for creating cloud volumes (cinder provider) in CloudForms does not filter cloud tenants by user. An attacker with the ability to create storage volumes could use this to create storage volumes for any other tenant.
