https://notcve.org/view.php?id=CVE-2018-17247

Elasticsearch Security versions 6.5.0 and 6.5.1 contain an XXE flaw in Machine Learning's find_file_structure API. If a policy allowing external network access has been added to Elasticsearch's Java Security Manager then an attacker could send a specially crafted request capable of leaking content of local files on the Elasticsearch node. This could allow a user to access information that they should not have access to.

Si se ha añadido una política que permite acceso externo a la red al gestor de seguridad Java de Elasticsearch Security, un atacante podría enviar una petición especialmente manipulada capaz de filtrar contenido de archivos locales en el nodo de Elasticsearch. • http://www.securityfocus.com/bid/106294 https://discuss.elastic.co/t/elastic-stack-6-5-2-security-update/159594 https://www.elastic.co/community/security • CWE-611: Improper Restriction of XML External Entity Reference •
