CVE-2024-32754

Device-identifier disclosure via setup-mode broadcasts

Published Jul 4, 2024 · Updated Aug 27, 2025

Information exposure in Johnson Controls Kantech KT controllers allows attackers to read device identifiers via local-network broadcasts. In factory-reset mode, the controller broadcasts its MAC address, serial number, and firmware version while awaiting initial setup. The disclosure requires adjacent-network access during that temporary state and stops after configuration.
