CVE-2024-14033Network attack vector

Device crash via legacy TLS session establishment

Published Apr 2, 2026 · Updated Apr 2, 2026

Denial of service in Belden Hirschmann EagleSDV 05.4.01 allows remote attackers to crash devices during TLS session establishment. The firmware crashes when establishing a session with TLS 1.0 or TLS 1.1, but Belden has not disclosed the faulty operation within the TLS implementation. No authentication or user interaction is required; the documented consequence is an availability interruption rather than data access or modification.
