Vulnerabilities in CODESYS software could have serious implications considering that it’s used in the industrial control systems (ICS) made by several major companies. Last month, a cybersecurity firm warned that programmable logic controllers (PLCs) made by over a dozen manufacturers were exposed to attacks due to critical security bugs discovered in CODESYS software.

CODESYS on July 22 published six new advisories to inform customers that patches are available for remote code execution, denial of service (DoS), and information disclosure vulnerabilities affecting its Development System, V3 web server, Gateway, Runtime Toolkit for VxWorks, and EtherNetIP products.
