Uncontrolled Resource Consumption can be exploited to cause the HMI to become unresponsive and not accurately update the display content (Denial of Service).
Uncontrolled Resource Consumption can be exploited to cause the Phoenix Contact HMIs BTP 2043W, BTP 2070W and BTP 2102W in all versions to become unresponsive and not accurately update the display content (Denial of Service).
When the HMI is subjected to i.e. a rapid flood of ICMP ping packets, the HMI stops responding to user input and the running program provides no visual changes. Once the attack stops, the HMI will return to normal functionality.
