CVE-2024-14026
Published: 11 March 2026
Summary
CVE-2024-14026 is a low-severity OS Command Injection (CWE-78) vulnerability in Qnap Quts Hero. Its CVSS base score is 2.0 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked at the 3.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-6 (Least Privilege) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2024-14026 is a command injection vulnerability (CWE-78) affecting several versions of QNAP operating systems, including QTS and QuTS hero. Published on 2026-03-11, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H), indicating high impact potential with low complexity and privileges required.
The vulnerability can be exploited by an attacker who has obtained local network access and a user account on the affected system. Successful exploitation allows the execution of arbitrary commands, enabling high levels of compromise in confidentiality, integrity, and availability.
QNAP has fixed the vulnerability in QTS 5.1.9.2954 build 20241120 and later, QTS 5.2.3.3006 build 20250108 and later, QuTS hero h5.1.9.2954 build 20241120 and later, and QuTS hero h5.2.3.3006 build 20250108 and later.

Why these techniques?
Command injection (CWE-78) directly enables arbitrary Unix shell command execution (T1059.004) and facilitates local privilege escalation (T1068) from low-privileged accounts.

Directly addresses the command injection vulnerability by requiring timely flaw remediation through patching to the fixed QNAP versions, preventing exploitation.
Prevents command injection by enforcing validation of user inputs at system interfaces before they are processed as commands.
Limits the impact of arbitrary command execution by ensuring user accounts operate with least privilege, reducing potential damage from local network exploitation.
