The MAC address filter as part of the firewall has a flaw, which prevents the MAC address filter to be active after restart. In this way a remote attacker is able to circumvent the MAC address filtering after a reboot of a device.
This Advisory is published with reference to:
During the installation of specific TRUMPF Windows applications, privileged local users with default usernames and passwords are created. An adversary could use these users to access and compromise the affected Windows systems and, under certain circumstances, other network resources.
The FTP server does not properly release memory resources that were reserved for incomplete connection attempts by FTP clients. This could allow a remote attacker to generate a denial of service condition on devices that incorporate a vulnerable version of the FTP server.
