The affected controllers do not properly sanitize the input containing code syntax. As a result, an attacker could craft code to alter the intended controller flow of the software.
Fixes

Solution

Affected users should contact a Trane representative to install updated firmware or request additional information. Please reference Trane service database number HUB-205962 when contacting the Trane office. Tracer SC is no longer actively developed, tested, or sold. Tracer SC will be considered end-of-life on December 31, 2022. Trane recommends identifying a migration plan for replacing the Tracer SC controller with the next-generation Tracer SC+ controller. Tracer SC+ can function as a drop-in replacement for Tracer SC, providing significant updates to security capabilities. Trane has identified the following specific mitigations: Tracer SC: Upgrade to v4.4 SP7 or later Tracer SC+: Upgrade to v5.5 SP3 or later Tracer Concierge: Upgrade to v5.5 SP3 or later
