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
Tec4Data SmartCooler, all versions prior to firmware 180806, the device responds to a remote unauthenticated reboot command that may be used to perform a denial of service attack.

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

The Tec4Data SmartCooler HVAC management device contains an authentication bypass vulnerability in versions prior to firmware 180806 that allows remote unauthenticated attackers to send reboot commands, causing denial of service.

MitigationUpdate SmartCooler firmware to version 180806 or later to patch the vulnerability.

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/documentation to confirm it is a Tec4Data SmartCooler HVAC management device.
    Affected if The device is not a Tec4Data SmartCooler.
  2. Determine the installed firmware version
    Log into the SmartCooler administrative interface and navigate to the System Information or About page to view the firmware version number.
    Affected if The firmware version is displayed and is below 180806.
  3. Check firmware version via CLI if available
    If the device has a command-line interface, use the appropriate command (such as 'show version' or 'system info') to retrieve the firmware build number.
    Affected if The returned firmware version is less than 180806.
  4. Verify network exposure of management interface
    Scan the network to determine if the SmartCooler management web interface (typically ports 80/443 or custom HTTP ports) is exposed to untrusted networks.
    Affected if The management interface is accessible from untrusted networks without VPN or firewall protection.

The environment is affected if a Tec4Data SmartCooler device is running firmware version lower than 180806, as this version range contains the authentication bypass flaw allowing remote unauthenticated reboot commands.
