Descriptions

Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary directory with the default permissions for newly created files when installing a plugin from a URL, potentially allowing attackers with access to the system temporary directory to replace the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.

Jenkins 2.423 y anteriores, LTS 2.414.1 y anteriores crean un archivo temporal en el directorio temporal del sistema con los permisos predeterminados para archivos recién creados al instalar un complemento desde una URL, lo que potencialmente permite a los atacantes con acceso al directorio temporal del sistema reemplazar el archivo antes de instalarlo en Jenkins, lo que podría provocar la ejecución de código arbitrario.
