Remediations
Mitigation
AVEVA recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.
Vendor fix
Users of affected product versions should apply security updates to mitigate the risk of proxy details exposure in newly generated PI to CONNECT Agent event logs.
Vendor fix
Users who have used affected product versions, should review existing PI to CONNECT Agent event logs (live/backups/copies) for exposed proxy connection details and consider purging the sensitive data from logs and/or configuring new credentials for access to the proxy service.
Mitigation
The following general defensive measures are recommended:
Mitigation
Remove use of plain text passwords in proxy URLs. Alternatively, if passwords are required by the proxy, then use least-privilege credentials.
Mitigation
Ensure only trusted users are given Event Log Reader (S-1-5-32-573) privileges on hosts where PI to CONNECT is installed.
Mitigation
Review existing PI to CONNECT event logs (live/backups/copies) for exposed proxy connection details and consider purging the sensitive data from logs and/or configuring new credentials for access to the proxy service.
Vendor fix
All affected versions can be fixed by upgrading to PI to CONNECT Agent v2.5.2790 or higher. The latestversion of the agent can be downloaded from the CONNECT Data Services Portal here: https://datahub.connect.aveva.com/.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
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 current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. 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.
