#VU53693 Insufficiently protected credentials in Ceph - CVE-2020-27781
Published: June 1, 2021
Ceph
Red Hat Inc.
Description
The vulnerability allows a local user to gain access to credentials of other application users.
The vulnerability exists due to the way credentials sharing is implemented. 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.
