Data decryption via brute-force attacks
Published Aug 24, 2023 · Updated Oct 2, 2024
Inadequate encryption strength in QNAP QTS and QuTS hero allows local network clients to decrypt data through brute-force attacks. QNAP has not disclosed the affected cryptographic component, the weak primitive or parameter, or how attacker-controlled input reaches it. Exploitation requires local-network access and user interaction; the documented consequence is recovery of protected data, while broader effects remain unspecified.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=h4.5.* <h4.5.4.2476 build 20230728
- Affected versionversion=h5.1.* <h5.1.0.2424 build 20230609
