CVE-2022-27596Network attack vector

Unauthenticated code execution via SQL injection

Published Jan 30, 2023 · Updated Mar 27, 2025

SQL injection in QNAP QTS 5.0.1 and QuTS hero h5.0.1 allows remote attackers to execute malicious code via crafted network requests. QNAP maps the flaw to CWE-89 but does not disclose the affected endpoint, input parameter, or SQL query that mishandles untrusted data. No authentication or user interaction is required, and successful exploitation grants code execution with access to NAS data and services.
