Description Martin Prpič 2015-05-05 13:20:36 UTC

The following flaw was found in Keystone:

Eric Brown from VMware reported a vulnerability in Keystone. The backend_argument configuration option content is being logged, and it may contain sensitive information for specific backends (like a password for MongoDB). An attacker with read access to Keystone logs may therefore obtain sensitive data about certain backends. All Keystone setups are potentially impacted.

Comment 1 Martin Prpič 2015-05-05 13:23:31 UTC

Created openstack-keystone tracking bugs for this issue:

Affects: fedora-all [bug 1218642]
Affects: openstack-rdo [bug 1218644]

Comment 3 Garth Mollett 2015-07-28 06:28:49 UTC

Statement:

While this issue does occur in openstack-keystone packages as shipped in Red Hat Enterprise Linux OpenStack Platform versions 5 and 6 it is not believed to be exploitable as access to the keystone logs is restricted with file-system permissions.
