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
A flaw has been found in ADSLR NBR1005GPEV2 250814-r037c. This affects the function ap_macfilter_add of the file /send_order.cgi. Executing manipulation of the argument mac can lead to command injection. The attack may be performed from remote. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

A command injection vulnerability exists in the ap_macfilter_add function of /send_order.cgi on ADSLR NBR1005GPEV2 devices (firmware 250814-r037c). The 'mac' parameter is not properly sanitized before being used in OS command execution, allowing remote unauthenticated attackers to inject arbitrary shell commands.

MitigationImmediately restrict network access to the device's web interface (e.g., firewall/ACLs). Since the vendor did not respond, consider isolating the device or replacing it with a supported alternative. If external access is required, implement strict ACLs at the network perimeter.

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
    Locate the device label or check the web interface footer/admin page for the model number. Confirm it is an ADSLR NBR1005GPEV2 or Adslr B Qe2w401 device.
    Affected if The device model matches NBR1005GPEV2 or Qe2w401
  2. Determine the firmware version
    Access the device web administration interface and navigate to the system status or firmware upgrade page to view the installed firmware version. Alternatively, check the firmware file name if you have access to it.
    Affected if The firmware version is 250814-r037c or earlier
  3. Verify the web interface is accessible
    Attempt to access http://[device-ip]/send_order.cgi from an authorized management network. Confirm the CGI endpoint responds.
    Affected if The /send_order.cgi endpoint is reachable and responds to requests
  4. Check if MAC filtering feature is enabled
    Log into the device web interface and navigate to the wireless or MAC filtering settings section. Look for the MAC filter configuration.
    Affected if MAC filtering is enabled or configurable on the device

The device is affected if it is an ADSLR NBR1005GPEV2 or Qe2w401 model running firmware version 250814-r037c or earlier, and the web interface with /send_order.cgi is accessible.

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.

From vendor data
Upgrade available Upgrade to a release after 250814-r037c
Interim mitigation

Immediately restrict network access to the device's web interface (e.g., firewall/ACLs). Since the vendor did not respond, consider isolating the device or replacing it with a supported alternative. If external access is required, implement strict ACLs at the network perimeter.
