CVE-2023-39465 — Triangle MicroWorks SCADA Data Gateway Use of Hard-coded Cryptograhic Key Information Disclosure Vulnerability

High CVSS 7.5

Triangle MicroWorks SCADA Data Gateway Use of Hard-coded Cryptograhic Key Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Triangle MicroWorks SCADA Data Gateway. Authentication is not required to exploit this vulnerability. The specific flaw exists within the TmwCrypto class. The issue results from the usage of a hard-coded cryptograhic key and the usage of a hard-coded certificate. An attacker can leverage this vulnerability to disclose sensitive information. Was ZDI-CAN-20615.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
