ABB Automation Builder Gateway Vulnerability Exposes Industrial Control Systems
In February 2026, ABB disclosed a vulnerability (CVE-2024-41975) in its Automation Builder Gateway for Windows, affecting versions prior to 2.9.0. The gateway, by default, listens on all network adapters on port 1217, allowing unauthenticated remote access. This configuration enables attackers to scan for connected Programmable Logic Controllers (PLCs). While PLC user management typically prevents unauthorized access, if disabled, attackers could potentially interact with the PLCs. ABB addressed this issue in version 2.9.0 by restricting the gateway's default access to local connections. ([cisa.gov](https://www.cisa.gov/news-events/ics-advisories/icsa-25-133-04?utm_source=openai)) This incident underscores the critical importance of secure default configurations in industrial control systems. As cyber threats targeting operational technology environments increase, organizations must ensure that default settings do not expose systems to unnecessary risks. Regularly updating software and reviewing default configurations are essential steps in mitigating such vulnerabilities.
