The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has alerted of two security flaws impacting Rockwell Automation ControlLogix EtherNet/IP (ENIP) communication module models that could be exploited to achieve remote code execution and denial-of-service (DoS). "The results and impact of exploiting these vulnerabilities vary depending on the ControlLogix system configuration, but they could lead to denial or loss of control, denial or loss of view, theft of operational data, or manipulation of control for disruptive or destructive consequences on the industrial process for which the ControlLogix system is responsible," Draogos said . The list of flaws is as follows - CVE-2023-3595 (CVSS score: 9.8) - An out-of-bounds write flaw impacting 1756 EN2* and 1756 EN3* products that could result in arbitrary code execution with persistence on the target system through maliciously crafted common industrial protocol ( CIP ) messages. CVE-2023-3596 (CVSS score: 7.5
