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

Summary

Security researchers have identified widespread vulnerability issues in serial-to-IP converter devices used in industrial and operational technology environments. These devices, which bridge legacy serial machine interfaces to modern IP networks, contain both known and previously undisclosed vulnerabilities that are increasingly being targeted by attackers. The research highlights a critical security gap in OT infrastructure where these gateway devices often lack regular patching and security updates.
