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 injection vulnerability in Barco ClickShare CX-30/20, C-5/10, and ClickShare Bar Pro and Core models, running firmware before 2.21.1, allows physically proximate attackers or local admins to the webUI to trigger OS-level command execution as root.

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

Command injection vulnerability in Barco ClickShare CX-30/20, C-5/10, and ClickShare Bar Pro and Core devices running firmware before 2.21.1 allows physically proximate attackers or local admins with webUI access to achieve OS-level command execution as root.

MitigationUpdate firmware to version 2.21.1 or later. Restrict physical access to device interfaces and limit webUI admin accounts to trusted personnel only.

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 your ClickShare device model
    Access the device webUI admin panel or check the physical device label to confirm the exact model number (CX-30, CX-20, C-5, C-10, ClickShare Bar Pro, or ClickShare Core)
    Affected if The device model is one of: CX-30, CX-20, C-5, C-10, ClickShare Bar Pro, or ClickShare Core. Other models are not affected by this specific CVE.
  2. Determine the installed firmware version
    Log into the ClickShare web interface as administrator and navigate to the System Settings or Device Information page to view the current firmware version. Alternatively, access the admin API or device console if available.
    Affected if The firmware version is below 2.21.1 (for example, 2.20.x, 2.19.x, or earlier). Versions 2.21.1 and later are not affected.
  3. Verify webUI admin access is enabled
    Confirm that the web-based administration interface is accessible on the network. Check if admin credentials are configured and the webUI port (typically 443) is reachable.
    Affected if The webUI is exposed and accessible to untrusted users. The vulnerability requires either a local admin with webUI access or a physically proximate attacker to trigger command injection.
  4. Assess physical accessibility of the device
    Evaluate whether the device is located in an area accessible to unauthorized personnel, or whether physical ports and interfaces are exposed in shared/public spaces.
    Affected if Physical access to the device or its ports is possible for untrusted individuals. Physical proximity is listed as an attack vector for this vulnerability.

Your environment is affected if you have a Barco ClickShare CX-30/20, C-5/10, or ClickShare Bar Pro/Core device running firmware version before 2.21.1, with the webUI accessible to untrusted users or the device physically reachable by unauthorized individuals.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update firmware to version 2.21.1 or later. Restrict physical access to device interfaces and limit webUI admin accounts to trusted personnel only.

Recommended fix High confidence

Firmware version 2.21.1 or later for Barco ClickShare CX-30, CX-20, C-5, C-10, ClickShare Bar Pro, and ClickShare Core models

  1. 1. Identify the exact Barco ClickShare model (CX-30, CX-20, C-5, C-10, ClickShare Bar Pro, or ClickShare Core) in use
  2. 2. Access the ClickShare system's admin web interface
  3. 3. Navigate to the firmware or system settings section
  4. 4. Check the current firmware version running on the device
  5. 5. Download firmware version 2.21.1 or later from the official Barco support website (www.barco.com)
  6. 6. In the admin interface, select the option to upload or update firmware
  7. 7. Upload the downloaded firmware file and initiate the update process
  8. 8. Wait for the update to complete - do not power off the device during the update
Caveat Standard firmware update carries standard risks - ensure adequate downtime window and test in non-production environment before deploying to production units
