Upstream Fix: https://github.com/elasticsearch/elasticsearch/commit/bd0eb32d9c3c3f5b6e5f8630c859cd04bdcd4e06 Upstream Issue: https://github.com/elasticsearch/elasticsearch/issues/7151 Updating the severity, for Sam 1.x elasticsearch only listens on localhost, thus local access is required. For Satellite 6.x the installation process should include firewalling it to trusted local users only. As such this only scores 3.3 instead of 5.8 on the CVSS2 scoring. Statement: This issue affects the versions of elasticsearch as shipped with Red Hat Satellite 6.x and Subscription Asset Manager 1.x. Red Hat Product Security has rated this issue as having Low security impact. A future update may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/. Mitigation: As provided at http://www.elasticsearch.org/community/security/, Users should either set "http.cors.enabled" to false, or set "http.cors.allow-origin" to the value of the server that should be allowed access, such as localhost or a server hosting Kibana. Disabling CORS entirely with the former setting is more secure, but may not be suitable for all use cases. For Satellite 6.x and Sam 1.x you can simply firewall elasticsearch to trusted users only (e.g. root, katello, foreman).
