Four New Vulnerabilities in Phoenix Contact Industrial Switches

A series of newly disclosed vulnerabilities could allow an attacker to gain control of industrial switches.



Phoenix Contact has disclosed four vulnerabilities in switches in the FL SWITCH industrial line. The affected devices are typically used in automated processes at digital substations, oil and gas, maritime, and other industrial applications.

The vulnerabilities were discovered by Positive Technologies researchers Vyacheslav Moskvin, Semyon Sokolov, Evgeny Druzhinin, Ilya Karpov, and Georgy Zaytsev.

Two of the vulnerabilities, CVE-2018-10730 and CVE-2018-10731, could allow an attacker to run arbitrary code on a switch.

CVE-2018-10728 involves a buffer overflow that could be exploited to perform a DoS attack, disable web and telnet services, or run arbitrary code, while CVE-2018-10729 would allow an unauthorized user to read the contents of the switch config file.

The vulnerabilities affect FL SWITCH models 3xxx, 4xxx, and 48xxx running firmware versions 1.0–1.33. The vendor strongly recommends updating to firmware version 1.34 as remediation for the vulnerabilities.
