Serial-to-IP Devices Hide Thousands of Old and New Bugs

### Executive Summary Forescout researchers disclosed multiple critical remote-code-execution vulnerabilities and numerous other high-/low-severity flaws in popular serial-to-IP converters and found that individual firmware images typically contain hundreds to thousands of known open-source and kernel vulnerabilities; because these devices bridge legacy industrial equipment and IP networks, successful exploitation could enable takeover, data manipulation (e.g., altered sensor/barcode readings), and disruption of OT/SCADA operations across many sectors.
