Descriptions

Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Between versions 2.3.0 and 2.8.2, the `doc` module of Icinga Web 2 allows to view documentation directly in the UI. It must be enabled manually by an administrator and users need explicit access permission to use it. Then, by visiting a certain route, it is possible to gain access to arbitrary files readable by the web-server user. The issue has been fixed in the 2.9.0, 2.8.3, and 2.7.5 releases. As a workaround, an administrator may disable the `doc` module or revoke permission to use it from all users.

Icinga Web 2 es una interfaz web de monitorización de código abierto, un framework y una interfaz de línea de comandos. Entre las versiones 2.3.0 y 2.8.2, el módulo "doc" de Icinga Web 2 permite ver la documentación directamente en la UI. Debe ser habilitado manualmente por un administrador y los usuarios necesitan un permiso de acceso explícito para utilizarlo. Entonces, al visitar una determinada ruta, es posible obtener acceso a archivos arbitrarios legibles por el usuario del servidor web. El problema se ha corregido en las versiones 2.9.0, 2.8.3 y 2.7.5. Como solución alternativa, un administrador puede desactivar el módulo "doc" o revocar el permiso de uso a todos los usuarios
