Critical CODESYS Vulnerabilities in Festo Automation Suite
⚠ CISA warns that multiple critical vulnerabilities affect CODESYS components bundled with Festo Automation Suite, including several issues rated CVSS 3.1 9.8. Affected installations include FAS releases prior to 2.8.0.138 and FAS 2.8.0.137 when using CODESYS 3.0 or 3.5.16.10; beginning with FAS 2.8.0.138, CODESYS is no longer bundled and must be installed separately. Vendors recommend updating to CODESYS Development System 3.5.21.20, applying Festo updates, avoiding untrusted project files, and minimizing network exposure of control systems.
