CVE-2023-34347Network attack vector

Administrator code execution via Device-Gateway deserialization

Published Jul 10, 2023 · Updated Nov 8, 2024

Deserialization in Delta Electronics InfraSuite Device Master before 1.0.7 allows remote attackers to execute arbitrary code. The Device-Gateway service on TCP port 3100 deserializes user-supplied data without proper validation. Authentication is not required, and successful exploitation runs attacker-controlled code in an administrator context.
