Remedy

For ICRL-M-8RJ45/4SFP-G-DIN and ICRL-M-16RJ45/4CP-G-DIN: Update to Firmware 1.3.1 and deactivate TFTP-Service. For all other devices: An external protective measure is required. 1) Traffic from untrusted networks to the device should be blocked by a firewall. Especially traffic targeting the administration webpage. 2) Administrator and user access should be protected by a secure password and only be available to a very limited group of people.
