CVE-2023-50705Network attack vector

Unauthenticated web-server information disclosure via crafted requests

Published Dec 19, 2023 · Updated Aug 2, 2024

Information disclosure in Efacec UC 500E 10.1.0 allows remote attackers to read web-server details via crafted requests. Public CISA and CNA material does not identify the affected web endpoint, request fields, or validation error that returns the information. Exploitation requires network reachability but no authentication or user interaction, and the published impact is limited to disclosure rather than modification or service interruption.
