FKIE_CVE-2026-1776

Vulnerability from fkie_nvd - Published: 2026-03-10 07:38 - Updated: 2026-04-17 20:59
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
Camaleon CMS versions 2.4.5.0 through 2.9.0, prior to commit f54a77e, contain a path traversal vulnerability in the AWS S3 uploader implementation that allows authenticated users to read arbitrary files from the web server’s filesystem. 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.

El problema ocurre en la funcionalidad download_private_file cuando la aplicaci\u00f3n est\u00e1 configurada para usar el backend CamaleonCmsAwsUploader. A diferencia de la implementaci\u00f3n 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 trav\u00e9s del par\u00e1metro file. Como resultado, cualquier usuario autenticado, incluidos los usuarios registrados con pocos privilegios, puede acceder a archivos sensibles como /etc /passwd. Este problema representa una omisi\u00f3n de la correcci\u00f3n incompleta para CVE-2024-46987 y afecta a las implementaciones que utilizan el backend de almacenamiento de AWS S3."
