A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, and corrupt snapshot images.
This would require user to have read access and for that user must have key for authentication. It would only affect snapshots and images. So attacker with read access will only be able to corrupt data of snapshot images and rest of the ceph cluster should work as it is. Affect on integrity would be low and availability part can be controlled by mitigation using 'monallowpooldelete = false' in ceph.conf to disable deletion of pools
