CVE-2023-39465Network attack vector

Sensitive-data disclosure via hard-coded cryptographic material

Published May 3, 2024 · Updated Aug 2, 2024

Information disclosure in Triangle MicroWorks SCADA Data Gateway 5.1.3.20324 allows remote attackers to read sensitive data without authentication. The TmwCrypto class uses a hard-coded cryptographic key and certificate instead of installation-specific trusted material. Network access to an affected gateway is sufficient; published details do not identify the exact exposed data or protocol request.
