Additional Advisory Data
Solutions
CNA: All affected versions can be fixed by upgrading to AVEVA Pipeline Simulation 2025 SP1 P01 (build 7.1.9580.8513) or higher: https://softwaresupportsp.aveva.com/en-US/downloads/products/details/57b79fdb-7b5f-4125-8a44-833b6b5c6d6f
Workarounds
CNA: AVEVA recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Customers using affected product versions should apply security updates to mitigate the risk of exploit.
CNA: The following general defensive measures are recommended: • Restrict Network Access: Implement host-based and/or network firewall controls on all nodes hosting the Pipeline Simulation Server API to ensure that only trusted Pipeline Simulation client systems are permitted to establish connections. • Enforce Secure Communication: Enable TLS for all API communications and ensure that server certificates are properly managed and protected to reduce the risk of manipulator-in-the-middle (MitM) attacks and tampering with data in transit.
