Incorrect handling request with non-standard symbols allows remote attackers to initiate a complete lock up of the bus coupler. Authentication of the request is not required.
The device stops responding to any network or local port, consequently shutting down this part of the automation system. The bus coupler needs to be restarted by disconnecting the power supply.
Customers using affected Phoenix Contact AXL F BK are recommended to operate the devices in closed networks or protected with a suitable firewall.
