CVE-2023-23367Network attack vector

Administrator command execution via undisclosed injection

Published Nov 10, 2023 · Updated Feb 26, 2025

OS command injection in QNAP QTS 5.0.x, QuTS hero h5.0.x, and QuTScloud c5.x allows remote authenticated users to execute commands. QNAP has not published the affected component, input field, or command-construction operation that fails to neutralize attacker-controlled data. Administrator access to the network interface is required, and exploitation executes operating-system commands with the affected service's privileges.
