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
Cambium Enterprise Wi-Fi System Software before 6.4.2 does not sanitize the ping host argument in device-agent.

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

This is an OS command injection vulnerability in Cambium Enterprise Wi-Fi System Software's device-agent component. The ping host argument is not sanitized, allowing an attacker to inject arbitrary shell commands by manipulating the ping parameter. This could allow complete compromise of the affected device.

MitigationUpgrade to Cambium Enterprise Wi-Fi System Software version 6.4.2 or later which contains the fix. Until upgraded, restrict network access to the device-agent management interface and disable the ping functionality if possible.

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 if Cambium Enterprise Wi-Fi software is installed
    Check system for Cambium Enterprise Wi-Fi System Software components, typically found in /opt/cambium or similar installation directories. Look for device-agent binary or service.
    Affected if Cambium Enterprise Wi-Fi software is present on the system
  2. Determine installed software version
    Run command to query the Cambium Enterprise Wi-Fi software version, such as 'device-agent --version' or check version file in installation directory.
    Affected if Version is lower than 6.4.2 (e.g., 6.4.1, 6.3.x, etc.)
  3. Verify device-agent component is running
    Check if the device-agent process or service is active on the system using 'ps aux | grep device-agent' or systemctl status for the device-agent service.
    Affected if device-agent component is running and accessible
  4. Confirm ping functionality is accessible
    Check if ping feature is exposed through device-agent management interface, typically via web UI port or API endpoint for ping functionality.
    Affected if Ping feature is enabled and reachable without authentication restrictions

System is affected if Cambium Enterprise Wi-Fi software version is below 6.4.2 AND the device-agent ping functionality is exposed or accessible.

Upgrade available Upgrade to 6.4.2 or later
Fixed in 6.4.2
Interim mitigation

Upgrade to Cambium Enterprise Wi-Fi System Software version 6.4.2 or later which contains the fix. Until upgraded, restrict network access to the device-agent management interface and disable the ping functionality if possible.

Recommended fix Moderate confidence

Enterprise Wi-Fi System Software version 6.4.2 or later

  1. 1. Check the current version of Cambium Enterprise Wi-Fi System Software by accessing the device management interface or running: version check command
  2. 2. Navigate to the official Cambium Networks support portal at www.cambiumnetworks.com or community.cambiumnetworks.com
  3. 3. Download the Enterprise Wi-Fi System Software version 6.4.2 or later
  4. 4. Before upgrading, backup the current device configuration according to Cambium best practices
  5. 5. Upload the 6.4.2 (or later) firmware to the device through the management interface
  6. 6. After upgrade completes, verify the device-agent ping functionality works correctly
  7. 7. Confirm the new version is running: system should show version 6.4.2 or higher
