CVE-2020-8975Network attack vector

Unauthenticated sensitive information disclosure via web routes

Published Oct 17, 2022 · Updated May 12, 2025

Information disclosure in ZGR TPS200 NG 2.00 firmware and 1.01 hardware allows remote attackers to read sensitive system information via web routes. The integrated web server exposes sensitive system data when attackers request application routes whose URIs are known. Access requires network reachability to the web application but no account or user interaction, and the documented impact is confidentiality loss without integrity or availability effects.
