An inadequate encryption strength vulnerability has been reported to affect QNAP operating systems. If exploited, the vulnerability possibly allows local network clients to decrypt the data using brute force attacks via unspecified vectors. We have already fixed the vulnerability in the following versions: QTS 5.0.1.2425 build 20230609 and later QTS 5.1.0.2444 build 20230629 and later QTS 4.5.4.2467 build 20230718 and later QuTS hero h5.1.0.2424 build 20230609 and later QuTS hero h4.5.4.2476 build 20230728 and later
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.1, indicating it requires adjacent network access but requires specific conditions to be met though user interaction is required and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from qnap, from qnap organizations running these solutions should prioritize assessment and patching.
Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For qnap's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
