Red Hat Security Advisory 2015-0791-01 – Red Hat Enterprise OpenStack Platform Installer is a deployment management tool. It provides a web user interface for managing the installation and configuration of remote systems. Deployment of changes is performed using Puppet. Additionally, Dynamic Host Configuration Protocol, Domain Name System, Preboot Execution Environment, and Trivial File Transfer Protocol services can be provided. Controlling these services also enables provisioning of physical systems that do not yet have an operating system installed. It was discovered that the puppet manifests, as provided with the openstack-puppet-modules package, would configure the pcsd daemon with a known default password. If this password was not changed and an attacker was able to gain access to pcsd, they could potentially run shell commands as root.
