remediations

Vendor fix, mitigation, or workaround guidance, as published by each source.

A vendor fix is available.

  • FixedAutomation Builderabb_psirt

    The problem is corrected in the following product version: - Automation Builder 2.9.1 ABB recommends that customers apply the update at earliest convenience. Automation Builder 2.9.1 is available for download from the related download site.

  • FixedCODESYS Development Systemcodesys_psirt

    Update the following products to version 3.5.21.40. * CODESYS Development System When existing CODESYS project files are opened with a fixed CODESYS Development system version, the option keys "PageSettings" and "PrinterSettings" are now obsolete and will be reset. As a result printer and page settings will be lost and have to be reconfigured. Only these specific parts of "Project Options -> Page Setup" are dropped by the update. The configured Header, Footer, TitlePage and Document options will be kept. The CODESYS Development System can be downloaded and installed directly with the CODESYS Installer or be downloaded from the CODESYS Store. Alternatively, as well as for all other products, you will find further information on obtaining the software update in the CODESYS Update area https://www.codesys.com/download/.

  • Fixedwago_psirt

    Update to Firmware version 4.10.0 (FW32) or higher. For the latest Custom Firmware please contact the WAGO support.

  • MitigationCODESYS Development Systemcodesys_psirt

    Open/install CODESYS archives, projects and packages from trustworthy sources only.

  • WorkaroundAutomation Builderabb_psirt

    Workarounds are specific measures that a user can take to help block an attack, for example, temporarily disabling the vulnerable feature may remove the exposure with well-known impact on functionality. ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as “Impact of work-around”. The vulnerability can be closed by enabling local access only. See chapter “Recommended immediate actions” for details.

Vendor and ecosystem advisories describing this.

  • 3ADR011566ABB Automation Builder - Deserialization of untrusted data2026-09-28csaf · abb_psirtCH

    ABB is aware of vulnerabilities in the products versions listed as affected in the advisory. Automation Builder could execute arbitrary code by crafting the project file or project archive file.

  • Advisory2025-11_VDE-2025-101CODESYS Development System - Deserialization of Untrusted Data2025-12-01csaf · codesys_psirtDE

    A vulnerability has been discovered in the print engine of the CODESYS development system. If a CODESYS project file or archive file was crafted in a specific way, the CODESYS development system could execute arbitrary code when a user opens these files and configures the print/printer options or prints the project or parts of it. This arbitrary code would be executed in the context of the user who was tricked into opening the project.
