{"id":"UBUNTU-CVE-2021-4180","details":"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.","modified":"2025-10-24T04:50:01Z","published":"2022-03-23T20:15:00Z","upstream":["CVE-2021-4180"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-4180"},{"type":"REPORT","url":"https://bugs.launchpad.net/tripleo/+bug/1955397"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-4180"}],"affected":[{"package":{"name":"tripleo-heat-templates","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/tripleo-heat-templates@0.6.1-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python-tripleo-heat-templates","binary_version":"0.6.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-4180.json"}},{"package":{"name":"tripleo-heat-templates","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/tripleo-heat-templates@5.2.0-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python-tripleo-heat-templates","binary_version":"5.2.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-4180.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
