Exposure of Sensitive Information to an Unauthorized Actor in OpenStack tripleo-heat-templates
An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation. A patch is available on the master branch and anticipated to be part of version 11.6.1.
