Mitsubishi Electric’s FR Configurator2 inverter engineering software is affected by several vulnerabilities that can be exploited for information disclosure, arbitrary code execution, privilege escalation, and denial-of-service (DoS) attacks.
Advisories describing the vulnerabilities have been published this week by Applied Risk, the industrial cybersecurity firm that discovered the flaws, the U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA), and Mitsubishi Electric.
FR Configurator2 is a tool that allows users to set up, program, configure and monitor variable-frequency drives. According to CISA, the product is used worldwide, particularly in the critical manufacturing sector.
One of the flaws, classified as “high severity” and described as an issue related to XML external entity (XXE) processing, can be exploited by an attacker to read and steal arbitrary files from the targeted system. Exploitation involves getting the victim to open a specially crafted project file (.frc2).
Depending on the targeted platform, the vulnerability could also allow an attacker to execute arbitrary code in certain circumstances, Applied Risk said.

Another vulnerability in FR Configurator2 allows an attacker to cause the software to stop responding (i.e., enter a DoS condition) until it’s forcefully restarted. This weakness, classified as “medium severity,” can ..
