CVE-2023-42666Network attack vector

Web-server version disclosure via crafted requests

Published Oct 19, 2023 · Updated Sep 12, 2024

Information disclosure in DEXMA DexGate 20130114 allows remote attackers to obtain the web-server version through crafted requests. The request-handling path exposes the underlying web-server version, but CISA has not published the affected endpoint, parameters, or response field. No authentication or user interaction is required, and the disclosure supports targeted reconnaissance without altering data or service availability.
