CVE-2025-41744Network attack vector

Traffic interception via shared default TLS private key

Published Dec 2, 2025 · Updated Dec 2, 2025

Default TLS keys in Sprecher Automation SPRECON-E-C, -E-P, and -E-T3 allow remote attackers to intercept or alter web traffic. The integrated web server and other TLS-enabled services ship with the same factory certificate and private key on every device. Exploitation requires an on-path position and key material extracted from any device or firmware file, exposing credentials and configuration data to interception or manipulation.
