Vulnerability from fkie_nvd - Published: 2026-01-13 23:15 - Updated: 2026-01-20 18:03
Severity ?
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
e107 CMS version 3.2.1 contains a critical file upload vulnerability that allows authenticated administrators to override arbitrary server files through path traversal. The vulnerability exists in the Media Manager's remote URL upload functionality (image.php) where the upload_caption parameter is not properly sanitized. An attacker with administrative privileges can use directory traversal sequences (../../../) in the upload_caption field to overwrite critical system files outside the intended upload directory. This can lead to complete compromise of the web application by overwriting configuration files, executable scripts, or other critical system components. The vulnerability was discovered by Hubert Wojciechowski and affects the image.php component in the admin interface.

La vulnerabilidad existe en la funcionalidad de carga de URL remota del Administrador de Medios (image.PHP) donde el par\u00e1metro upload_caption no se sanitiza correctamente. Un atacante con privilegios administrativos puede usar secuencias de salto de directorio (../../../) en el campo upload_caption para sobrescribir archivos cr\u00edticos del sistema fuera del directorio de carga previsto. Esto puede llevar a un compromiso completo de la aplicaci\u00f3n web al sobrescribir archivos de configuraci\u00f3n, scripts ejecutables u otros componentes cr\u00edticos del sistema. La vulnerabilidad fue descubierta por Hubert Wojciechowski y afecta al componente image.PHP en la interfaz de administraci\u00f3n."
