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
An issue in dlink DNS-320 v.1.00 and DNS-320LW v.1.01.0914.20212 allows an attacker to execute arbitrary via the account_mgr.cgi->cgi_chg_admin_pw components.

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 · moderate confidence

Dlink DNS-320 and DNS-320LW NAS devices contain a vulnerability in the account_mgr.cgi web component (cgi_chg_admin_pw) that allows arbitrary code execution. The vulnerability is exploitable remotely with network access to the device's web interface.

MitigationRestrict network access to the NAS management interface, ideally placing it behind a firewall or VPN. Since these are older discontinued devices, verify if firmware updates exist; otherwise consider replacement with a supported device.

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. Identify the device model
    Access the device's web interface or check the device label/hardware to confirm it is a D-Link DNS-320 or DNS-320LW NAS. Alternatively, use network discovery to identify the device by its MAC address OUI (D-Link) and hostname.
    Affected if The device is a D-Link DNS-320 or DNS-320LW model.
  2. Verify web interface accessibility
    Determine if the device's web management interface (typically on port 80 or 443) is reachable from the network. Use a browser or curl to attempt access to the login page.
    Affected if The web interface is accessible from untrusted networks, indicating remote exploitation is possible.
  3. Check for account_mgr.cgi exposure
    Attempt to access the account_mgr.cgi endpoint directly (for example, /cgi-bin/account_mgr.cgi) to confirm the component is present and responding.
    Affected if The account_mgr.cgi endpoint is accessible, suggesting the vulnerable component is exposed.
  4. Confirm firmware version
    Log into the device web interface and navigate to the system status or firmware information page to identify the installed firmware version. Compare against any available firmware release notes.
    Affected if The installed firmware is an unpatched version of the DNS-320 or DNS-320LW firmware containing the vulnerability.

You are affected if you have a D-Link DNS-320 or DNS-320LW NAS with its web interface exposed to the network and the account_mgr.cgi component is accessible.

Mitigation

Restrict network access to the NAS management interface, ideally placing it behind a firewall or VPN. Since these are older discontinued devices, verify if firmware updates exist; otherwise consider replacement with a supported device.
