CVE-2022-4616
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 · uneditedThe webserver in Delta DX-3021 versions prior to 1.24 is vulnerable to command injection through the network diagnosis page. This vulnerability could allow a remote unauthenticated user to add files, delete files, and change file permissions.
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 confidenceThe Delta DX-3021 webserver versions prior to 1.24 contains a command injection vulnerability in the network diagnosis page that allows remote unauthenticated attackers to execute arbitrary commands, enabling file addition, deletion, and permission modification on the affected 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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device's web interface or check the device label/documentation to confirm the model is Delta DX-3021 or DX-3021l9.Affected if The device is a Delta DX-3021 series model.
-
Check the firmware versionLog into the webserver administrative interface and navigate to the System Info, About, or Firmware section to view the currently installed firmware version. Alternatively, check via CLI if available.Affected if The firmware version is displayed as lower than 1.24 or the version cannot be confirmed as 1.24 or later.
-
Verify network diagnosis page accessibilityAttempt to access the network diagnosis page on the webserver. This is typically found at a URL path related to network diagnostic functions or may be reachable without authentication.Affected if The network diagnosis page is accessible without authentication or login.
-
Check network exposureReview network access controls to determine if the device's management interface (port 80/443) is exposed to untrusted networks or the internet.Affected if The web management interface is reachable from untrusted networks or directly from the internet.
The device is affected if it is a Delta DX-3021 with firmware version prior to 1.24 AND the network diagnosis page is accessible, making command injection possible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.24
Upgrade Delta DX-3021 firmware to version 1.24 or later to patch the command injection vulnerability. If immediate patching is not possible, restrict network access to the device's management interface and disable the network diagnosis page if feasible.
Firmware version 1.24
- Obtain Delta DX-3021 firmware version 1.24 from the official Delta download center (downloadcenter.deltaww.com)
- Access the Delta DX-3021 device web interface
- Navigate to the firmware update or system maintenance section
- Upload and install firmware version 1.24
- Reboot the device as prompted
- Verify the firmware version displays as 1.24 after reboot
