QNAP TS-453D (TS-453D-8G)

Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	[1] 🔗 Proof	Physical reset and removable drives create a local tampering surface; the rating concerns exposure, not measured attack frequency.
Known vulnerabilities	Rare	[2] 🔗 Proof	CVE-2022-27596 affected QTS 5.0.1 before the cited fix; the model appears in an affected-build applicability list.
Prior attacks	Rare	[3] 🔗 Proof	DeadBolt campaigns are documented for the QNAP NAS platform; exact victims are not identified by model in these sources.
Updatability	Very common	[4] 🔗 Proof	The model is listed for QTS maintenance releases in December 2025 and July 2026.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	🔗 Proof	NFS AUTH_SYS provides host/user identity checks without requiring Kerberos mutual authentication in this configuration.
Communications	No encryption	[5] 🔗 Proof	HTTP management and NFS AUTH_SYS remain enabled in this configuration; these plaintext paths are not protected by optional HTTPS.
Storage	No encryption	[6] 🔗 Proof	The assessed user-data volume and share on internal SATA SSD flash are unencrypted, with no SED locking enabled.
Category Score	Score: 3 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Full	[7] [8] 🔗 Proof	QTS supports restricted local users, group/application permissions, user removal and password changes.
Authentication	Basic	[9] 🔗 Proof	Password-only login is assessed; the retained physical reset permits documented administrator account recovery.
Brute-force protection	Exist	🔗 Proof	HTTP(S) IP access protection is enabled and blocks clients after the configured failed-login limits.
Event logging	Access event logged	[10] [11] 🔗 Proof	QuLog Center access logging is enabled for HTTP(S), with a valid log destination in the assessed configuration.
Passwords	Require change after setup with complexity requirements	[12] 🔗 Proof	New local users must replace temporary passwords at first logon; the stated 12-character mixed-case/digit policy is enforced.
Category Score	Score: 2 / 3

Documentation-based security assessment: QNAP TS-453D. Reviewed 2026-10-24.

Documentation-based assessment of a defined QTS 5.2.10.3568 build 20260722 local-NAS configuration, not a factory-default or physical-test report. It uses native local users, password-only login, LAN HTTP management and an NFS AUTH_SYS share. Compatible internal SATA SSDs, with required mounting adapters, contain an unencrypted static user-data volume and an unencrypted shared folder; SED locking is not enabled. HTTP(S) IP access protection is enabled with configured failed-login and time limits. QuLog Center access logging is enabled for HTTP(S), with a destination on an unencrypted volume retaining more than 10 percent free space. The local password policy requires at least 12 characters, upper- and lower-case letters and digits, and newly created local users must change their temporary password at first logon. The documented physical basic-reset function is retained. These settings define the assessment case; no device was installed or tested.

Ratings map documented capabilities and the stated configuration to WikiIoT choices. Rare is a qualitative assessment of documented bounded exposure/history, not a measured frequency. Prior attacks is explicitly platform-level history; the sources do not identify each selected model as a confirmed victim, and some campaigns predate individual model releases. An enabled plaintext path is rated No encryption. Storage covers user data on internal SATA SSD flash, without inferring the state of every boot component. Optional capabilities are not treated as enabled unless the assessment configuration states so. Historical CVEs do not imply that the selected patched firmware remains vulnerable.

Release-date scope: 2020-06-23, from the global English TS-x53D launch; the hardware family announcement date, not a separately established first-sale date for each RAM SKU.

Historical vulnerability: CVE-2022-27596. QTS 5.0.1 before 5.0.1.2234 build 20221201. The model is listed for historical QTS 5.0.1.2194. QTS 5.0.1.2234 build 20221201 and later fix the issue. The selected QTS 5.2.10.3568 profile is not claimed to retain this vulnerability.

No physical device was tested. Keep the configuration and evidence scope with the ratings.
