If MAC-based port security or 802.1x port security is enabled, the FL NAT 2xxx will unintentionally grant access to unauthorized devices in case of routed transmission.

Subnet 2---(Ports belonging to subnet 2)
|
FL NAT 2xxx
|
(Ports belonging to subnet 1, port sec ON)---- 2nd device
|
-- unauthorized device

The unauthorized device can access other devices in subnet 2 but cannot access the 2nd device in subnet 1



Manipulated PC Worx or Config+ projects could lead to a remote code execution due to
insufficient input data validation.
The attacker needs to get access to an original PC Worx or Config+ project to be able to
manipulate data inside the project folder. After manipulation the attacker needs to exchange the
original files by the manipulated ones on the application programming workstation.



In case TwinCAT is configured to use the Profinet driver, a denial of service of the controller could be reached by sending special packets to the device.
