Vulnerability from csaf_cisa - Published: 2025-04-30 00:00 - Updated: 2026-05-21 06:00Summary
ABB Automation Builder (Update A)
Notes
Summary: ABB is aware of vulnerabilities in the product versions listed as affected in the following section.
An attacker who successfully exploited this vulnerability could overrule the Automation Builder’s user management. Workarounds to close the vulnerabilities are available.
Workarounds: 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 workaround”.
To exploit the vulnerabilities, access the project on file level is required. This can be prevented by the security settings of the Automation Builder projects, accessible via the menu “Project” → “Project
Settings…” → “Security”.
• CVE-2025-3394: In the project settings, set “Security” to “Integrity check”. This prevents anyone
to access or modify the content of the Automation Builder project file. Projects can be opened
and used without any limitations.
• CVE-2025-3395: In the project settings, set “Security” to “Encryption”. This prevents unauthorized users to open the project. Authorized users can open the project and with that exploit the
vulnerability
General security recommendations: For any installation of software related ABB products we strongly recommend the following (non-exhaustive) list of cyber security practices:
– Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls
and separate them from any general-purpose network (e.g. office or home networks).
– Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks.
– Never connect programming software or computers containing programing software to any network other than the network for the devices that it is intended for.
– Scan all data imported into your environment before use to detect potential malware infections.
– Minimize network exposure for all applications and endpoints to ensure that they are not accessible
from the Internet unless they are designed for such exposure and the intended use requires such.
– Ensure all nodes are always up to date in terms of installed software, operating system, and firmware
patches as well as anti-virus and firewall.
– When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

Support: For additional instructions and support please contact your local ABB service organization. For contact
information, see www.abb.com/contactcenters.
Information about ABB’s cyber security program and capabilities can be found at www.abb.com/cybersecurity.
Mitigating factors: Immediate workarounds to close the vulnerabilities are:
• CVE-2025-3394: In the project settings, set “Security” to “Integrity check”
• CVE-2025-3395: In the project settings, set “Security” to “Encryption”
ABB recommends that customers apply the workarounds at earliest convenience.
With the latest Automation Builder version (starting with version 2.8.1), the default for “Security” is set
to “Integrity check”. By keeping this default unchanged, CVE-2025-3394 cannot be exploited.
Legal Notice and Terms of Use: This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy).
Advisory Conversion Disclaimer: This ICSA is a verbatim republication of ABB PSIRT 3ADR011407 from a direct conversion of the vendor's Common Security Advisory Framework (CSAF) advisory. This is republished to CISA's website as a means of increasing visibility and is provided "as-is" for informational purposes only. CISA is not responsible for the editorial or technical accuracy of republished advisories and provides no warranties of any kind regarding any information contained within this advisory. Further, CISA does not endorse any commercial product or service. Please contact ABB PSIRT directly for any questions regarding this advisory.
Recommended Practices: CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Recommended Practices: Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Recommended Practices: Locate control system networks and remote devices behind firewalls and isolate them from business networks.
Recommended Practices: When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
Recommended Practices: CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices: CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices: CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Recommended Practices: Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
Critical infrastructure sectors: Energy
Countries/areas deployed: Worldwide
Company headquarters location: Switzerland
Automation Builder stores all user management information in the project file. Despite fully encrypted password data, an attacker could try to modify parts of the Automation Builder project file by specially crafted contents so that the user management will be overruled.
