CVE-2023-1138Network attack vector

Credential disclosure via unauthenticated Gateway configuration retrieval

Published Mar 27, 2023 · Updated Jan 16, 2025

Improper access control in Delta Electronics InfraSuite Device Master before 1.0.5 allows remote attackers to read Gateway configuration files. The Device-Gateway service on TCP port 80 fails to enforce access control before returning configuration data containing plaintext credentials. No authentication or user interaction is required, and successful retrieval exposes stored credentials that can enable further compromise.
