It's possible for an authenticated backoffice-user to enumerate and traverse paths/files on the systems filesystem and read their contents, on Mac/Linux Umbraco installations using Forms. As Umbraco Cloud runs in a Windows environment, Cloud users aren't affected. This issue affects versions 16 and 17 of Umbraco Forms and is patched in 16.4.1 and 17.1.1. If upgrading is not immediately possible, users can mitigate this vulnerability by configuring a WAF or reverse proxy to block requests containing path traversal sequences (`../`, `..\\`) in the `fileName` parameter of the export endpoint, restricting network access to the Umbraco backoffice to trusted IP ranges, and/or blocking the `/umbraco/forms/api/v1/export` endpoint entirely if the export feature is not required. However, upgrading to the patched version is strongly recommended."}, {"lang": "es", "value": "Umbraco Forms es un constructor de formularios que se integra con el sistema de gesti\u00f3n de contenidos Umbraco. Es posible que un usuario autenticado del backoffice enumere y recorra rutas/archivos en el sistema de archivos del sistema y lea su contenido, en instalaciones de Umbraco con Forms en Mac/Linux. Dado que Umbraco Cloud se ejecuta en un entorno Windows, los usuarios de Cloud no se ven afectados. Este problema afecta a las versiones 16 y 17 de Umbraco Forms y est\u00e1 parcheado en las versiones 16.4.1 y 17.1.1. Si la actualizaci\u00f3n no es posible de inmediato, los usuarios pueden mitigar esta vulnerabilidad configurando un WAF o un proxy inverso para bloquear las solicitudes que contengan secuencias de salto de ruta ('../', '..\\') en el par\u00e1metro 'fileName' del endpoint de exportaci\u00f3n, restringiendo el acceso a la red del backoffice de Umbraco a rangos de IP de confianza, y/o bloqueando completamente el endpoint '/umbraco/forms/API/v1/export' si la funci\u00f3n de exportaci\u00f3n no es necesaria.
