CVE-2024-50393Network attack vector

Unauthenticated arbitrary command execution

Published Dec 6, 2024 · Updated Dec 10, 2024

Command injection in QNAP QTS 5.1.x and 5.2.x and QuTS hero h5.1.x and h5.2.x allows remote attackers to execute arbitrary commands. QNAP has not disclosed the affected component, input field, command-construction path, or operation that fails to neutralize untrusted input. No privileges are required, but QNAP's assessment requires passive user interaction; command execution can compromise stored data and interrupt NAS services.
