What to do

Solution: AVEVA recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.  * 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.  * 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. The following general defensive measures are recommended:  * Remove use of plain text passwords in proxy URLs. Alternatively, if passwords are required by the proxy, then use least-privilege credentials.  * Ensure only trusted users are given Event Log Reader (S-1-5-32-573) privileges on hosts where PI to CONNECT is installed.  * 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. All affected versions can be fixed by upgrading to PI to CONNECT Agent v2.5.2790 or higher. The latest version of the agent can be downloaded from the CONNECT Data Services Portal here: [ https://www.aveva.com/content/dam/aveva/documents/support/cyber-security-updates/SecurityBulletin_AVEVA-2026-003.pdf .
