Description
A flaw was found in the `puppetlabs-cinder` module, as used in PackStack. This vulnerability is due to incorrect file permissions, specifically world-readable permissions, on the `cinder.conf` and `api-paste.ini` configuration files. A local user can exploit this by reading these files, which leads to the disclosure of OpenStack administrative passwords. This information disclosure could allow unauthorized access to sensitive OpenStack resources.
