CVE-2020-7499Network attack vector

Unauthorized changes via undisclosed authorization flaw

Published Jun 16, 2020 · Updated Aug 4, 2024

Incorrect authorization in Schneider Electric U.motion firmware before 1.4.2 allows remote authenticated users to make unauthorized changes. Schneider Electric identifies affected servers and touch panels and the authorization class, but does not disclose the request, endpoint, or permission check that accepts the low-privileged change. A low-privileged account and network access are required, and the bounded consequence is unauthorized modification without reported confidentiality or availability impact.
