Descriptions

Elasticsearch Alerting and Monitoring in versions before 6.4.1 or 5.6.12 have an information disclosure issue when secrets are configured via the API. The Elasticsearch _cluster/settings API, when queried, could leak sensitive configuration information such as passwords, tokens, or usernames. This could allow an authenticated Elasticsearch user to improperly view these details.

Elasticsearch Alerting and Monitoring en versiones anteriores a la 6.4.1 o 5.6.12 tiene una vulnerabilidad de divulgación de información cuando los secretos se configuran mediante la API. La API Elasticsearch _cluster/settings, cuando se hace una consulta, podría filtrar información de configuración sensible como contraseñas, tokens o nombres de usuario. Esto podría permitir que un usuario de Elasticsearch autenticado visualice indebidamente estos detalles.
