CVE-2023-25948Network attack vector

Configuration disclosure via crafted-message error response

Published Jul 13, 2023 · Updated Mar 5, 2025

Information disclosure in Honeywell Experion products allows remote attackers to read configuration data via crafted messages. The server message-error path returns configuration data after processing a specially crafted message instead of limiting the response to error details. No authentication or user interaction is required, and Honeywell has not disclosed the affected protocol or handler.
