AVEVA Application Server IDE Cross-Site Scripting Risk
⚠ AVEVA reported a basic cross-site scripting vulnerability (CVE-2025-8386) in the Application Server IDE affecting versions 2023 R2 SP1 P02 and earlier. An authenticated user with the aaConfigTools privilege can modify App Objects' help files to persist XSS that may execute in other users' sessions, potentially enabling horizontal or vertical privilege escalation. AVEVA provides a fix in System Platform 2023 R2 SP1 P03; CISA advises auditing permissions, minimizing network exposure, and using secure remote access methods.
