Disable the posibility to establish unauthenticated sessions to the OPC UA server, because the atttack works on an established OPC UA session.
Remove the optional methods „ResendData“ (ns=0;i=12873 and ns=0;i=12871) und „GetMonitoredItems“ (ns=0;i=11492 and ns=0;i=11489) from address space. Only these methods are affected. Or call the method Application::instance()->setEnableServiceGroup(EnumServiceGroup_Methods, false) during the server initialization to disable all OPC UA methods.
