CVE-2023-46663Network attack vector

Protected-resource disclosure via unchecked HTTP requests

Published Oct 26, 2023 · Updated Jan 16, 2025

Improper access control in Sielco PolyEco1000 allows remote attackers to access protected resources via crafted HTTP requests. The web application interface accepts action-bearing requests without validating them or enforcing authorization before serving the protected resource. No credentials or user interaction are required; the published impact is limited to protected-information disclosure, with no integrity or availability effect reported.
