These shortcomings fall under the following broad categories -\\n\\n * Remote code execution – CVE-2026-32955, CVE-2026-32956, CVE-2026-32961, CVE-2025-67041, CVE-2025-67034, CVE-2025-67035, CVE-2025-67036, CVE-2025-67037, and CVE-2025-67038\\n * Client-side code execution – CVE-2026-32963\\n * Denial-of-service (DoS) – CVE-2026-32961, CVE-2015-5621, CVE-2024-24487\\n * Authentication bypass – CVE-2026-32960, CVE-2025-67039\\n * Device takeover – FSCT-2025-0021 (no CVE assigned), CVE-2026-32965, CVE-2025-70082\\n * Firmware tampering – CVE-2026-32958\\n * Configuration tampering – CVE-2026-32962, CVE-2026-32964\\n * Information disclosure – CVE-2026-32959\\n * Arbitrary file upload – CVE-2026-32957\\n\\n\\n\\n\\n\\nSuccessful exploitation of the aforementioned flaws could allow attackers to disrupt serial communications with field assets, conduct lateral movement, and tamper with sensor values or modify actuator behavior.\\n\\nIn a hypothetical attack scenario, a threat actor could gain initial access to a remote facility through an internet-exposed edge device, such as an industrial router or firewall, and then weaponize BRIDGE:BREAK vulnerabilities to compromise the serial-to-IP converter, and alter serial data moving to or from the IP network.\\n\\nLantronix and Silex have released security updates to address the identified issues -\\n\\n * Lantronix EDS3000PS Series\\n * Lantronix EDS5000 Series\\n * Silex\\n\\n\\n\\nBesides applying patches, users are advised to replace default credentials, avoid using weak passwords, segment networks to prevent bad actors from reaching vulnerable serial-to-IP converters or using them as jumping-off points to other critical assets, and ensure the devices are not exposed to the internet.\\n\\n\\”This research highlights weaknesses in serial-to-IP converters and the risks they can introduce in critical environments,\\” Forescout said. \\”As these devices are increasingly deployed to connect legacy serial equipment to IP networks, vendors and end-users should treat their security implications as a core operational requirement.\\”\\n\\nFound this article interesting?
