Security readout for executives and security teams

This issue affects AzeoTech DAQFactory versions before 5.85 Build 1842. Certain remote signals were not authenticated, allowing an attacker to cause a denial of service by rebooting or shutting down the system. For operational environments, the main business risk is unplanned process or monitoring interruption. Exposure is most likely in legacy DAQFactory deployments older than 5.85 Build 1842, especially if signal handling interfaces are reachable from untrusted or poorly segmented networks. The bundle does not identify platforms, CPEs, or configuration prerequisites. Treat as a targeted availability risk for environments still running legacy DAQFactory. It is not KEV-listed in the provided bundle, but unauthenticated remote shutdown or reboot capability can still disrupt monitoring or industrial operations. Mitigation focus: Inventory DAQFactory deployments and identify versions older than 5.85 Build 1842.; Check AzeoTech guidance and revision history for the appropriate fixed release path.; Restrict DAQFactory signaling interfaces to trusted operational networks only..
