Descriptions

The zip API endpoint in Cerberus FTP Server 8 allows an authenticated attacker without zip permission to use the zip functionality via an unrestricted API endpoint. Improper permission verification occurs when calling the file/ajax_download_zip/zip_name endpoint. The result is that a user without permissions can zip and download files even if they do not have permission to view whether the file exists.

La comprobación de permisos inapropiada ocurre cuando se llama al endpoint file/ajax_download_zip/zip_name. El resultado es que un usuario sin permisos puede comprimir y descargar archivos inclusive si no tiene permiso para visualizar si el archivo existe.
