Thousands of Vulnerabilities Found in Serial-to-IP Devices

Researchers identified thousands of vulnerabilities in serial-to-IP devices, which convert machine communications into internet-compatible protocols, making them frequent targets for attacks in operational technology (OT) environments. These devices are riddled with both old and newly discovered flaws, though specific CVE IDs, affected vendors, or exact vulnerability counts were not disclosed. The security issues expose critical infrastructure to potential exploitation, increasing risks in industrial control systems (ICS) and OT networks. No specific dates or timelines for disclosure or patching were provided in the report. The findings highlight a growing trend of attackers targeting these translation devices due to their role as intermediaries between legacy and modern systems.
