Summary
Pepperl+Fuchs: Multiple VDM100-Distance Ethernet-IP sensors with multiple vulnerabilities
Notes
Summary: Critical vulnerabilities have been discovered in the utilized component TRECK TCP/IP Stack by Digi International Inc. For more information see advisory by Digi International Inc.: Digi International Security Notice - TRECK TCP/IP Stack "RIPPLE20" VU#257161 ICS-VU-035787 | Digi International
Impact: Pepperl+Fuchs analyzed and identified affected devices. The impact on the affected device is that it can - no longer perform acyclic requests - may drop all established cyclic connections may - disappear completely from the network
