Published May 29, 2026 · Updated May 29, 2026

The published advisory identifies the Administration WebUI but does not disclose the affected request, parameter, handler, or command construction path. High-privileged WebUI access is required; exploitation executes commands on the TX Host and can compromise its data, configuration, and availability.
