Descriptions

All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed.

Todas las versiones de Samba anteriores a 4.13.16, son vulnerables a que un cliente malicioso use una carrera SMB1 o NFS para permitir la creación de un directorio en un área del sistema de archivos del servidor no exportada bajo la definición del recurso compartido.
