CVSS 3.1
4.3 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:NCVE-2021-4180
Medium (4.3). EPSS 0.8% chance of exploitation in the next 30 days. Fixed in tripleo-heat-templates 11.6.1.
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. This flaw affects openstack-tripleo-heat-templates versions prior to 11.6.1.
