The vulnerability, if exploited, could allow an authenticated miscreant
(with privilege of "aaConfigTools") to tamper with App Objects' help
files and persist a cross-site scripting (XSS) injection that when
executed by a victim user, can result in horizontal or vertical
escalation of privileges. The vulnerability can only be exploited during
config-time operations within the IDE component of Application Server.
Run-time components and operations are not affected.

Solution

AVEVA recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Users using affected product versions should apply security updates to mitigate the risk of exploit. All affected versions of the Application Server IDE can be fixed by upgrading to AVEVA System Platform 2023 R2 SP1 P03 https://softwaresupportsp.aveva.com/en-US/downloads/products/details/d32b2534-9601-4beb-ac78-046ca2ef594d  or higher. The following general defensive measures are recommended: * Audit assigned permissions to ensure that only trusted users are added to the "aaConfigTools" OS Group. For additional information on Application Server OS Security groups and accounts, see https://docs.aveva.com/bundle/sp-install/page/738031.html For more information, see AVEVA's Security Bulletin AVEVA-2025-005 https://www.aveva.com/content/dam/aveva/documents/support/cyber-security-updates/SecurityBulletin_AVEVA-2025-005.pdf or AVEVA's bulletins page https://www.aveva.com/en/support-and-success/cyber-security-updates/ .
