CVE-2023-39981Network attack vector

Unauthenticated disclosure of device information

Published Sep 2, 2023 · Updated Oct 28, 2024

Improper authentication in Moxa MXsecurity Series 1.0 through 1.0.1 allows remote attackers to disclose device information through the web service. Moxa identifies the web service as the entry point and the weakness as missing authentication for a critical function, but publishes no affected endpoint or failed validation operation. No credentials or user interaction are required, and the reported consequence is limited to unauthorized device-information disclosure.
