CVE-2024-14026 — QTS, QuTS hero

A command injection vulnerability has been reported to affect several QNAP operating system versions. If an attacker gains local network access who have also gained a user account, they can then exploit the vulnerability to execute arbitrary commands. We have already fixed the vulnerability in the following versions: 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 QuTS hero h5.2.3.3006 build 20250108 and later

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.6% (30-day exploitation probability)+7
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Qnap Qts, Qnap Quts Hero, QNAP Systems Inc. QTS…).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Vendor, product and versions as the sources word them.
