CVE-2020-27781

User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator.

Red Hat OpenStack Platform deployments use the ceph package directly from the Ceph channel; the RHOSP package will not be updated at this time.

Red Hat OpenShift Container Storage (RHOCS) 4 shipped ceph package for the usage of RHOCS 4.2 only, that has reached End Of Life. The shipped version of ceph package is no longer used and supported with the release of RHOCS 4.3.

Red Hat Enterprise Linux ceph packages do not include the vulnerable component.
