Schneider Electric published a set of security advisories covering multiple EcoStruxure and Modicon product lines, with impacts ranging from remote code execution to loss of confidentiality and integrity and security policy bypass. Affected products named across the notices include EcoStruxure Foxboro DCS, EcoStruxure Automation Expert, EcoStruxure IT Data Center Expert, EcoStruxure Power Monitoring Expert, EcoStruxure Power Operation Advanced Reporting and Dashboards Module, and several Modicon PLC families. National cyber agencies in Canada and France urged organizations to review Schneider Electric bulletins and apply vendor-provided mitigations and updates.
One of the disclosed issues, tracked by CISA for EcoStruxure Foxboro DCS, is a deserialization of untrusted data flaw (CWE-502) affecting workstation and server components in versions prior to CS8.1; Schneider said Control Core Services and runtime components such as FCPs, FDCs, and FBMs are not affected. The vulnerability can enable loss of confidentiality and integrity and possible remote code execution if an administrator-authenticated user opens a malicious project file on a vulnerable workstation. The broader March advisory set references CVE-2025-11739, CVE-2025-13957, CVE-2026-1286, and CVE-2026-2273, and defenders are being told to prioritize patching alongside standard ICS protections such as network segmentation, firewalling, restricted access, and secured remote connectivity.
