CVE-2023-41292Network attack vector

Authenticated code execution via unchecked buffer copy

Published Feb 2, 2024 · Updated Jun 17, 2025

Buffer overflow in QNAP QTS 5.1.x, QuTS hero h5.1.x, and QuTScloud c5.x allows remote authenticated users to execute code via a network request. The operating systems copy attacker-controlled input into a buffer without checking its size; QNAP has not identified the affected component or operation. Administrative privileges and network access are required, and the published impact is limited to code execution with low integrity and availability effects.
