A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
