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 vulnerability was found in H3C Magic NX15, Magic NX30 Pro, Magic NX400, Magic R3010 and Magic BE18000 up to V100R014. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /api/wizard/getDualbandSync of the component HTTP POST Request Handler. The manipulation leads to command injection. The attack needs to be done within the local network. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component.

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 HTTP POST Request Handler for the /api/wizard/getDualbandSync endpoint on H3C Magic NX15, NX30 Pro, NX400, R3010, and BE18000 routers up to V100R014. An attacker within the local network can inject arbitrary commands through manipulated POST requests to this API endpoint.

MitigationUpgrade affected H3C Magic router models to the latest firmware version beyond V100R014. Restrict network access to the affected API endpoints and monitor for indicators of compromise given the public exploit availability.

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 router model
    Access the router admin panel or check the device label to confirm the exact model (NX15, NX30 Pro, NX400, R3010, or BE18000)
    Affected if Model is one of NX15, NX30 Pro, NX400, R3010, or BE18000
  2. Check firmware version
    In the router admin panel, navigate to System Settings, Status, or About page to view the current firmware version. Compare it to V100R014.
    Affected if Firmware version is at or below V100R014 (for example, V100R013, V100R012)
  3. Verify API endpoint accessibility
    From a machine on the same local network, attempt to reach http://<router-ip>/api/wizard/getDualbandSync using a GET or empty POST request to confirm the endpoint responds.
    Affected if The endpoint responds with any JSON or error message, indicating it is exposed
  4. Confirm local network exposure
    Verify the router is accessible from devices on the internal network without authentication restrictions on the /api/wizard/ path.
    Affected if The router API is reachable from internal network hosts without requiring authentication for that endpoint

If the router model is H3C Magic NX15, NX30 Pro, NX400, R3010, or BE18000 and the firmware version is V100R014 or lower with the /api/wizard/getDualbandSync endpoint accessible, the environment is affected by CVE-2025-2731.

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

Upgrade affected H3C Magic router models to the latest firmware version beyond V100R014. Restrict network access to the affected API endpoints and monitor for indicators of compromise given the public exploit availability.

Recommended fix Moderate confidence

Latest firmware version newer than V100R014 from official H3C support (specific version number to be confirmed from H3C advisories)

  1. 1. Identify the current firmware version of the H3C Magic device by accessing the web administration interface or checking the device label
  2. 2. Visit the official H3C support website (www.h3c.com or zhiliao.h3c.com) and locate the firmware download section for your specific model (Magic NX15, NX30 Pro, NX400, R3010, or BE18000)
  3. 3. Download the latest firmware version that is newer than V100R014
  4. 4. Access the device's web administration panel and navigate to the firmware upgrade or system settings section
  5. 5. Upload and apply the new firmware version, ensuring the device remains powered on throughout the process
  6. 6. After the upgrade completes, verify the new firmware version is installed and test that the /api/wizard/getDualbandSync functionality works properly
  7. 7. Confirm the vulnerability is remediated by checking that command injection is no longer possible through the affected endpoint
Caveat Firmware upgrades may reset device configuration; backup settings before upgrading and reapply after successful upgrade
