An advisory released earlier this month by Japan’s JPCERT/CC revealed that the product is affected by five use-after-free and out-of-bounds vulnerabilities, all with a CVSS score of 7.8.

CX-Programmer, which is part of Omron’s CX-One automation software suite, is designed for programming and debugging Omron programmable logic controllers (PLCs). According to the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the product is used worldwide, including in the critical manufacturing sector.

The CX-Programmer vulnerabilities affect version 9.76.1 and earlier. The flaws were discovered by security researcher Michael Heinzl, who told SecurityWeek that his findings were reported to the vendor in May and June 2021 through JPCERT/CC.
