Solution

Fixed in FOX61x R15A or XMC20 R15A


Workaround

Recommended security practices and firewall configurations help protecting systems from attacks that originate from outside the network. Such practices include that network management systems and FOX61x or XMC20 networks are typically physically protected from direct access by unauthorized personnel and have no direct connections to the Internet, as well as are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system.
