CVE-2021-28112
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 · uneditedDraeger X-Dock Firmware before 03.00.13 has Active Debug Code on a debug port, leading to remote code execution by an authenticated attacker.
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 confidenceThe Draeger X-Dock firmware versions prior to 03.00.13 contain active debug code exposed through a debug port. An authenticated attacker can leverage this debug interface to execute arbitrary code remotely, potentially gaining full control of the device.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 installed firmware versionAccess the device management interface or use the vendor-provided diagnostic tool to retrieve the current firmware version. This is typically found in the device settings, system information, or through a firmware version query command.Affected if The installed firmware version is any version prior to 03.00.13 (e.g., 03.00.12, 03.00.10, etc.)
-
Locate debug service documentation or configurationReview the device configuration files, service listings, or network service mappings to identify if a debug interface or debug port service is present and running on the device.Affected if A debug port service or debug interface is found to be actively running or exposed on the device.
-
Verify debug port accessibilityCheck network configuration or port scans of the device to determine if the debug port is accessible from network interfaces. This may involve checking open ports, firewall rules, or service bindings.Affected if The debug port is accessible from network interfaces or is not disabled in the device configuration.
A user is affected if their Draeger X-Dock firmware version is below 03.00.13 AND the debug port/interface is exposed or enabled on the device.
Generated from the published advisory. Verify against your own configuration.
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 · scoped03.00.13
Update Draeger X-Dock firmware to version 03.00.13 or later to remove the debug code. If immediate patching is not possible, restrict network access to the device and ensure strong authentication controls are in place to limit exposure to authenticated attackers.
03.00.13
- Obtain the Draeger X-Dock Firmware version 03.00.13 or later from the official Draeger source (static.draeger.com or authorized channels)
- Review Draeger documentation for firmware upgrade procedures specific to X-Dock devices
- Follow the manufacturer's recommended firmware update process to upgrade the X-Dock device to firmware version 03.00.13 or newer
- Verify the firmware upgrade was successful by checking the device version information
- Ensure the device is properly re-secured after upgrade (review authentication settings, disable any unnecessary debug features if re-enabled)
