Trane Tracer SC Family: Multiple High-Risk Vulnerabilities
⚠️ CISA published an advisory for Trane Tracer SC, Tracer SC+, and Tracer Concierge reporting five vulnerabilities that could lead to information disclosure, arbitrary command execution, or denial-of-service. The issues (CVE-2026-28252 through CVE-2026-28256) include broken cryptography, excessive memory allocation, missing authorization, and hard-coded credentials/constants. Affected builds include Tracer SC < v4.4_SP7 and Tracer SC+/Concierge < v6.3.2310; Trane released Tracer SC+ v6.30.2313 to address these flaws. CISA advises isolating control networks, restricting remote access, applying vendor updates, and following ICS defensive best practices.
