The +vulnerability allowed users to obtain access to arbitrary portions of +the CephFS filesystem hierarchy instead of being properly restricted +to their own subvolumes. The vulnerability is due to a bug in the +"volumes" plugin in Ceph Manager. This plugin is responsible for +managing Ceph File System subvolumes, which are used by OpenStack +Manila services as a way to provide shares to Manila users. + +Again, this vulnerability impacts only OpenStack Manila clusters that +provided native CephFS access to their users. + +Affected versions +----------------- + +Any version of Ceph running OpenStack Manila that was upgraded from Nautilus +or earlier. + +Fixed versions +-------------- + +* Quincy v17.2.2 (and later) +* Pacific v16.2.10 (and later) +* Octopus fix is forthcoming + +Recommendations +--------------- + +#. Users should upgrade to a patched version of Ceph at their earliest + convenience. + +#. Administrators who are + concerned they may have been impacted should audit the CephX keys in + their cluster for proper path restrictions. |
