CVE-2023-2024Network attack vector

Unauthenticated sensitive-data access via unprotected API calls

Published May 18, 2023 · Updated Feb 12, 2025

Improper authentication in Johnson Controls OpenBlue Enterprise Manager Data Collector before 3.2.5.75 allows remote attackers to read sensitive data. Under certain circumstances, API calls reach protected collector data without performing authentication, exposing sensitive information to an unauthorized requester. No credentials or user interaction are required; the published material does not identify the affected endpoints or additional conditions that trigger the bypass.
