Threats Tagged 'cve-2026-28252'

CVE-2026-28252 is a critical vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge systems caused by the use of a broken or risky cryptographic algorithm. This flaw enables attackers to bypass authentication mechanisms and gain root-level access without requiring user interaction or prior privileges. The vulnerability has a high CVSS 4.0 score of 9.2, reflecting its severe impact on confidentiality, integrity, and availability. Although no known exploits are currently in the wild, the risk remains significant due to the critical nature of the affected systems, which are widely used in building automation and HVAC control. The vulnerability requires network access but has a high attack complexity, meaning exploitation is possible but may require some effort. Organizations using these Trane products should prioritize patching or mitigating this issue to prevent unauthorized control of critical infrastructure components. Countries with extensive deployment of Trane building management systems and critical infrastructure reliance on HVAC automation are at heightened risk. Immediate mitigation steps include network segmentation, restricting access to management interfaces, and monitoring for anomalous authentication attempts.
