Host data disclosure via uninitialized memory
Published Jun 11, 2025 · Updated Jun 11, 2025
Information disclosure in Johnson Controls iSTAR Configuration Utility before 6.9.5 allows attackers to read Windows PC data via adjacent access. The vendor maps the issue to use of an uninitialized variable but does not disclose the responsible function or input path. No authentication or user interaction is required, but access is limited to an adjacent network; exposure is confined to data from the host PC.
