Germany-based industrial solutions provider Phoenix Contact last week informed customers that a total of 10 vulnerabilities have been identified across several of the company's products.
According to advisories published by Phoenix Contact and Germany's , which coordinates cybersecurity issues related to industrial automation, the vulnerabilities were reported to the company by various researchers and companies.
Phoenix Contact's TC router, FL MGUARD modules, ILC 2050 BI building controllers, and PLCNext products are affected by two vulnerabilities: a high-severity security bypass issue and a medium-severity denial of service flaw.
SMARTRTU AXC remote terminal and automation systems, CHARX control modular AC charging controllers, EEM-SB37x energy meters, and PLCNext products are impacted by a high-severity vulnerability that can be exploited to install malicious firmware on a device.
Phoenix Contact's ILC1x1 industrial controllers are affected by a high-severity DoS vulnerability that can be triggered using specially crafted IP packets.
"Phoenix Contact Classic Line industrial controllers are developed and designed for the use in closed industrial networks. The communication protocols and device access do not feature authentication measures. Remote attackers can use specially crafted IP packets to cause a denial of service on the PLC's network communication module," the vendor said in its advisory.
