Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in I-O DATA network attached hard disk 'HDL-T Series' firmware Ver.1.21 and earlier when 'Remote Link3 function' is enabled. If exploited, a remote unauthenticated attacker may execute an arbitrary OS command.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OS command injection vulnerability in I-O DATA HDL-T Series NAS firmware versions 1.21 and earlier. When the Remote Link3 function is enabled, improper input validation allows remote unauthenticated attackers to inject and execute arbitrary OS commands on the affected device.

MitigationUpgrade HDL-T Series firmware to a version beyond Ver.1.21. If immediate patching is not possible, disable the Remote Link3 function as a temporary workaround to reduce the attack surface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device is HDL-T Series NAS
    Identify the I-O DATA HDL-T Series network-attached storage device on your network. Check the device label, web interface, or management console for the product model.
    Affected if Device is an I-O DATA HDL-T Series NAS
  2. Check firmware version
    Access the NAS web management interface and navigate to the system settings or firmware information page. Identify the installed firmware version.
    Affected if Firmware version is 1.21 or earlier
  3. Verify Remote Link3 status
    Access the NAS web management interface and locate the Remote Link3 configuration settings. Check whether the Remote Link3 function is currently enabled or disabled.
    Affected if Remote Link3 function is enabled

Device is affected if it is an I-O DATA HDL-T Series NAS running firmware version 1.21 or earlier with the Remote Link3 function enabled.

Mitigation

Upgrade HDL-T Series firmware to a version beyond Ver.1.21. If immediate patching is not possible, disable the Remote Link3 function as a temporary workaround to reduce the attack surface.
