The HKSVA028V20 is typically identified as a high-performance or Motion Control Interface Unit . Designed for precision applications, this unit serves as the bridge between the main controller (PLC) and the mechanical servo motor.
| Product | Versions Affected | |---------|-------------------| | (stand‑alone) | 2.8.0‑2.0 through 2.8.0‑2.0‑hotfix‑5 | | SecureSync Gateway (reverse‑proxy) | 2.8.0‑2.0 (gateway component forwards the vulnerable RPC) | | SecureSync Client (Windows) | No direct impact – client merely forwards crafted payloads to the server. | | Linux / macOS Server builds | Same as Windows – the flaw resides in the cross‑platform C++ core library ( syncsvc.dll / libsyncsvc.so ). | hksva028v20
The "028V" designation often hints at voltage specifications or power handling capabilities, usually aligning with standard industrial voltage ranges (e.g., 24V DC logic or 220V/380V AC main power, depending on the specific manufacturer series). | | Linux / macOS Server builds |

| Symptom | Likely Cause | Fix | | :--- | :--- | :--- | | | No power supply, or Pin 4 not enabled. | Measure Vcc to GND; should be ~20V. Connect Pin 4 to Vcc. | | Output stuck at 10V | Open circuit in sensor element or magnetic overload. | Remove magnetic field. If output stays high, replace sensor. | | Non-linear output | Ground loop or insufficient decoupling. | Add a 100nF ceramic capacitor between Vcc and GND near the sensor. Use star grounding. |
