Summary
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions prior to 2.11.10 and from version 2.12.0 through version 2.12.4, some of the Icinga 2 features that require credentials for external services expose those credentials through the API to authenticated API users with read permissions for the corresponding object types. IdoMysqlConnection and IdoPgsqlConnection (every released version) exposes the password of the user used to connect to the database. IcingaDB (added in 2.12.0) exposes the password used to connect to the Redis server. ElasticsearchWriter (added in 2.8.0)exposes the password used to connect to the Elasticsearch server. An attacker who obtains these credentials can impersonate Icinga to these services and add, modify and delete information there. If credentials with more permissions are in use, this increases the impact accordingly. Starting with the 2.11.10 and 2.12.5 releases, these passwords are no longer exposed via the API. As a workaround, API user permissions can be restricted to not allow querying of any affected objects, either by explicitly listing only the required object types for object query permissions, or by applying a filter rule.

         value: "Icinga es un sistema de monitorización que comprueba la disponibilidad de los recursos de la red, notifica a los usuarios de las interrupciones y genera datos de rendimiento para informes. En las versiones anteriores a 2.11.10 y desde versión 2.12.0 hasta versión 2.12.4, algunas de las funcionalidades de Icinga 2 que requieren credenciales para servicios externos exponen dichas credenciales mediante la API a los usuarios autenticados de la API con permisos de lectura para los tipos de objetos correspondientes. IdoMysqlConnection y IdoPgsqlConnection (cada versión liberada) expone la contraseña del usuario usado para conectarse a la base de datos. IcingaDB (añadido en versión 2.12.0) expone la contraseña usada para conectarse al servidor Redis. ElasticsearchWriter (añadido en versión 2.8.0) expone la contraseña usada para conectarse al servidor Elasticsearch. Un atacante que obtenga estas credenciales puede hacerse pasar por Icinga a estos servicios y añadir, modificar y eliminar información allí. Si las credenciales con más permisos están en uso, el impacto aumenta acorde. A partir de las versiones 2.11.10 y 2.12.5, estas contraseñas ya no están expuestas por medio de la API. Como solución, los permisos de usuario de la API pueden restringirse para no permitir la consulta de los objetos afectados, ya sea enumerando explícitamente sólo los tipos de objetos requeridos para los permisos de consulta de objetos o aplicando una regla de filtro",
