CVE-2023-38422Network attack vector

Sensitive-data disclosure via unauthenticated management API

Published Aug 23, 2023 · Updated Oct 3, 2024

Missing authentication in Walchem Intuition 9 firmware before 4.21 allows remote attackers to download and export sensitive data. The controller's management web server serves some API download and export routes without validating an authenticated session. Network access to the web server is sufficient; the public record limits the impact to disclosure and does not identify the affected route names.
