  "title": "Firmware authenticity verification flaw in Schneider Electric Sage RTUs",
  "summary": "Schneider Electric Sage RTU 1410, 1430, 1450, 2400, 3030 Magnum, and 4400 devices are affected by inadequate verification of firmware authenticity during updates. An attacker able to influence a firmware update initiated by an authorized administrator could install altered firmware and gain control of the device.",
  "mitigation": "Restrict firmware-update permissions to necessary administrators, obtain update images only through trusted channels, and verify their integrity before deployment. Isolate affected RTUs from untrusted networks and monitor or approve firmware-update activity until a vendor update is available.",
