CVE-2022-21938Network attack vector

Stored script execution via unsanitized Draft Graphics

Published Jun 15, 2022 · Updated Sep 16, 2024

Stored cross-site scripting in Johnson Controls Metasys ADS/ADX/OAS 10 and 11 allows remote authenticated users to run script in MUI Graphics. The MUI Graphics interface accepts malicious code in Draft Graphics content and stores it for later rendering without adequate neutralization. High-privilege access is required to plant the payload, and another user must open the affected graphic, exposing that user's browser-held data and actions.
