22 BRIDGE:BREAK flaws hit Lantronix and Silex Technology converters, exposing approximately 20,000 devices to hijacking and data tampering.
Researchers at Forescout Research Vedere Labs found 22 BRIDGE:BREAK flaws in serial-to-IP devices from Lantronix and Silex Technology.
Serial-to-IP converters, also known as serial device servers, connect legacy serial equipment to modern IP networks for remote monitoring and control. They are widely used in sectors like energy (RTUs, relays), industry (PLCs), retail (POS systems), and healthcare (patient monitors). These devices allow organizations to integrate older hardware into TCP/IP networks without replacing existing systems, improving connectivity while extending equipment lifespan.
The experts warn that around 20,000 devices sit exposed online. Attackers can take control of these converters and manipulate the data they transmit, creating serious risks for industrial and enterprise environments.
“We discovered 22 new vulnerabilities in hardware from device makers: Lantronix and Silex.” reads the report published by Forescout. “Also known as ‘serial-to-IP’ and ‘serial device servers’, these innocuous ‘bridge’ devices are exploitable across critical infrastructure industries, including utilities, healthcare, manufacturing, retail, financial services, transportation, and more.”
“Some of these vulnerabilities allow attackers to take full control of mission-critical devices connected via serial links.” added the company.
Researchers analyzed firmware from major serial-to-IP vendors and found widespread security issues. Each device included dozens of software components, thousands of known vulnerabilities, and many existing exploits. A deeper review uncovered 22 new flaws in Lantronix and Silex…
