Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-13086 is an exposure of sensitive information vulnerability (CWE-200) affecting QNAP's QTS and QuTS hero operating systems. The issue enables remote attackers to access sensitive data, potentially compromising system security. It impacts versions prior to the patched releases, with the vulnerability formally published on March 7, 2025, and assigned a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
Remote, unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows disclosure of limited sensitive information without impacting integrity or availability, thereby enabling partial compromise of the affected system's security posture.
QNAP has addressed the vulnerability through patches in QTS 5.2.0.2851 build 20240808 and later, as well as QuTS hero h5.2.0.2851 build 20240808 and later. Security practitioners should prioritize updating affected devices, with full details available in the vendor advisory at https://www.qnap.com/en/security-advisory/qsa-25-03.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized actors from obtaining sensitive information.
Information flow enforcement structurally prevents sensitive data from reaching unauthorized recipients.
Protection of information at rest prevents unauthorized exposure of stored sensitive data.
Transmission confidentiality mechanisms stop exposure of sensitive data on the wire.
Least privilege reduces the set of actors who can reach sensitive information.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.10 only requires awareness, a topic-specific acceptable-use policy stating expected behaviours/monitoring, and procedures referencing classification and other controls; per the owner's explicit rule on labelling and similar dependency-style clauses, this does not itself prevent exposure (CWE-200) unless access/DLP/etc. act on it.
Requiring the return of all physical and electronic assets plus secure deletion of organizational data from personal devices reduces the chance that sensitive information remains accessible to departing personnel.
A.5.12 only defines and communicates a classification scheme so that protection needs can be understood; per the owner's explicit rule, labeling/classification does not itself prevent exposure and requires other controls (e.g. access enforcement) to act on it.
By requiring classification labels and metadata on all information assets, the control makes it harder for sensitive data to be inadvertently exposed because downstream systems and users can recognize and enforce handling rules based on those labels.
Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.
Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
