Remote service interruption via uncontrolled resource consumption
Published Dec 19, 2024 · Updated Dec 20, 2024
Uncontrolled resource consumption in QTS, QuTS hero, and QuTScloud allows remote attackers to interrupt affected NAS services. QNAP has not disclosed the affected component, resource, or network input whose processing consumes resources without an enforced limit. No authentication or user interaction is required, but attack complexity is high; the reported impact is limited to denial of service, with no reported data disclosure or modification.
