CVE-2022-3382Network attack vector

Unauthenticated controller disconnection via command-source handling

Published Oct 17, 2022 · Updated Apr 16, 2025

Improper access control in HIWIN Robot System Software 3.3.21.9869 allows remote attackers to disconnect HRSS from its controller. Command-source handling fails to properly address a terminated command source, but the affected interface, message format, and validation logic remain undisclosed. No authentication or user interaction is required; exploitation interrupts robot-controller communication without reported data disclosure or modification.
