Descriptions

When creating or updating credentials for single-user access, Apache NiFi wrote a copy of the Login Identity Providers configuration to the operating system temporary directory. On most platforms, the operating system temporary directory has global read permissions. NiFi immediately moved the temporary file to the final configuration directory, which significantly limited the window of opportunity for access. NiFi 1.16.0 includes updates to replace the Login Identity Providers configuration without writing a file to the operating system temporary directory.

Cuando son creadas o actualizadas las credenciales para el acceso de un solo usuario, Apache NiFi escribe una copia de la configuración de los proveedores de identidad de inicio de sesión en el directorio temporal del sistema operativo. En la mayoría de las plataformas, el directorio temporal del sistema operativo presenta permisos de lectura globales. NiFi movió inmediatamente el archivo temporal al directorio de configuración final, lo que limitó significativamente la ventana de oportunidad de acceso. NiFi versión 1.16.0 incluye actualizaciones para sustituir la configuración de los proveedores de identidad de inicio de sesión sin escribir un archivo en el directorio temporal del sistema operativo
