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
Barco TransForm NDN-210 Lite, NDN-210 Pro, NDN-211 Lite, and NDN-211 Pro before 3.8 allows Command Injection (issue 1 of 4). The NDN-210 has a web administration panel which is made available over https. The logon method is basic authentication. There is a command injection issue that will result in unauthenticated remote code execution in the username and password fields of the logon prompt. The NDN-210 is part of Barco TransForm N solution and includes the patch from TransForm N version 3.8 onwards.

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

Unauthenticated command injection in the web-based login form of Barco TransForm NDN-210/211 series devices. Attackers can execute arbitrary OS commands via the username and password fields without any authentication, due to improper input sanitization in the basic authentication mechanism.

MitigationUpgrade all affected Barco TransForm NDN-210/211 devices to version 3.8 or later. If immediate patching is not feasible, network-segment or firewall the admin interface to restrict access from untrusted networks.

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 web administrative interface and look for the device model identifier in the system information or status page, or check the physical device label on the NDN-210/211 unit
    Affected if The device is not a Barco TransForm NDN-210 or NDN-211 series unit
  2. Check the installed firmware version
    Log into the web administrative interface and navigate to the firmware or system information section to view the current software version, or use the command-line interface if available
    Affected if The firmware version is below 3.8 (for example, 3.7.x or earlier)
  3. Verify web-based login is accessible
    Attempt to access the device web interface over HTTP/HTTPS by navigating to the device IP address. The vulnerability is in the login form, so confirm the basic authentication login page is reachable
    Affected if The web login form is accessible from your network without authentication
  4. Confirm basic authentication is enabled
    Inspect the HTTP response headers or authentication configuration on the web login page. The vulnerability exploits the basic authentication mechanism in the username and password fields
    Affected if Basic authentication is the configured method for the web login interface

Your environment is affected if you have a Barco TransForm NDN-210 or NDN-211 device running firmware version below 3.8 with the web administrative interface accessible on your network.

dbcve · scoped
Upgrade available Upgrade to 3.8 or later
Fixed in 3.8
Interim mitigation

Upgrade all affected Barco TransForm NDN-210/211 devices to version 3.8 or later. If immediate patching is not feasible, network-segment or firewall the admin interface to restrict access from untrusted networks.

Recommended fix High confidence

TransForm N version 3.8

  1. Identify the specific Barco TransForm N model (NDN-210 Lite, NDN-210 Pro, NDN-211 Lite, or NDN-211 Pro) in your environment
  2. Check the current firmware version of the affected device
  3. Navigate to Barco's official support website (www.barco.com) and locate the firmware download section for TransForm N
  4. Download the TransForm N version 3.8 or later firmware update
  5. Review Barco's firmware upgrade documentation and ensure compliance with any prerequisites
  6. Apply the firmware update following Barco's official upgrade procedure for the specific device model
  7. After rebooting, verify the device is running version 3.8 or later
  8. Confirm the web administration panel is accessible and the basic authentication login form no longer accepts command injection payloads
