The issue occurs in the download_private_file functionality when the application is configured to use the CamaleonCmsAwsUploader backend. Unlike the local uploader implementation, the AWS uploader does not validate file paths with valid_folder_path?, allowing directory traversal sequences to be supplied via the file parameter. As a result, any authenticated user, including low-privileged registered users, can access sensitive files such as /etc/passwd. This issue represents a bypass of the incomplete fix for CVE-2024-46987 and affects deployments using the AWS S3 storage backend."},{"lang":"es","value":"Las versiones 2.4.5.0 a 2.9.0 de Camaleon CMS, anteriores al commit f54a77e, contienen una vulnerabilidad de salto de ruta en la implementación del cargador de AWS S3 que permite a los usuarios autenticados leer archivos arbitrarios del sistema de archivos del servidor web. El problema ocurre en la funcionalidad download_private_file cuando la aplicación está configurada para usar el backend CamaleonCmsAwsUploader. A diferencia de la implementación del cargador local, el cargador de AWS no valida las rutas de archivo con valid_folder_path?, permitiendo que se suministren secuencias de salto de directorio a través del parámetro file. Como resultado, cualquier usuario autenticado, incluidos los usuarios registrados con pocos privilegios, puede acceder a archivos sensibles como /etc /passwd.
