FKIE_CVE-2025-64523
Vulnerability from fkie_nvd - Published: 2025-11-12 23:15 - Updated: 2026-10-19 13:10
Severity
Summary
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Versions prior to 2.45.1 have an Insecure Direct Object Reference (IDOR) vulnerability in the FileBrowser application's share deletion functionality. This vulnerability allows any authenticated user with share permissions to delete other users' shared links without authorization checks. The impact is significant as malicious actors can disrupt business operations by systematically removing shared files and links. This leads to denial of service for legitimate users, potential data loss in collaborative environments, and breach of data confidentiality agreements. In organizational settings, this could affect critical file sharing for projects, presentations, or document collaboration. Version 2.45.1 contains a fix for the issue.

"value": "File Browser proporciona una interfaz de gesti\u00f3n de archivos dentro de un directorio especificado y puede utilizarse para cargar, eliminar, previsualizar, renombrar y editar archivos. Las versiones anteriores a la 2.45.1 tienen una vulnerabilidad de Referencia Directa a Objeto Insegura (IDOR) en la funcionalidad de eliminaci\u00f3n de recursos compartidos de la aplicaci\u00f3n FileBrowser. Esta vulnerabilidad permite a cualquier usuario autenticado con permisos de recurso compartido eliminar los enlaces compartidos de otros usuarios sin comprobaciones de autorizaci\u00f3n. El impacto es significativo ya que los actores maliciosos pueden interrumpir las operaciones comerciales eliminando sistem\u00e1ticamente archivos y enlaces compartidos. Esto conduce a la denegaci\u00f3n de servicio para usuarios leg\u00edtimos, posible p\u00e9rdida de datos en entornos colaborativos y el incumplimiento de los acuerdos de confidencialidad de datos. En entornos organizacionales, esto podr\u00eda afectar el intercambio cr\u00edtico de archivos para proyectos, presentaciones o colaboraci\u00f3n de documentos. La versi\u00f3n 2.45.1 contiene una soluci\u00f3n para el problema."
