Unauthenticated account enumeration via response discrepancy
Published Oct 11, 2022 · Updated May 15, 2025
Observable response discrepancy in Johnson Controls C•CURE 9000 2.90 and earlier allows remote attackers to enumerate user accounts. The C•CURE Portal produces distinguishable responses for account queries, but Johnson Controls has not disclosed the specific endpoint or response difference. No authentication or user interaction is required, but reachability is limited to an adjacent network and the reported consequence is account-name disclosure only.
