Credential disclosure via captured local SMB traffic
Published Aug 20, 2025 · Updated Sep 9, 2025
Information exposure in Schneider Electric EcoStruxure Building Operation products allows man-in-the-middle attackers to capture SMB credentials. Schneider Electric has not disclosed which component emits the credentials or why SMB traffic makes them observable. A valid user must communicate locally over SMB within the BMS network; the consequence is limited to credential disclosure.
