Descriptions

In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using MultipartFormDataParser creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used.

En Jenkins versión 2.423 y anteriores, LTS versión 2.414.1 y anteriores, el procesamiento de cargas de archivos utilizando MultipartFormDataParser crea archivos temporales en el directorio temporal predeterminado del sistema con los permisos predeterminados para archivos recién creados, lo que potencialmente permite a los atacantes con acceso al sistema de archivos del controlador Jenkins leer y escriba los archivos antes de usarlos.
