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 has been found in JD Cloud BE6500 4.4.1.r4308. This issue affects the function sub_4780 of the file /jdcapi. Such manipulation of the argument ddns_name leads to command injection. The attack may be performed from remote. The exploit has been disclosed to the public 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 · moderate confidence

Command injection vulnerability in JD Cloud BE6500 router firmware version 4.4.1.r4308 allows remote attackers to inject arbitrary commands via the ddns_name parameter in the /jdcapi file function sub_4780. The vulnerability is exploitable remotely without authentication and has public exploit code available.

MitigationApply vendor firmware update when available; until then, restrict network access to the device's management interface, disable external facing services if possible, or implement network segmentation/ACLs to limit exposure to trusted networks only.

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. Confirm device model
    Access the router web interface admin panel or inspect the device label/boot logs to verify the hardware is a JD Cloud BE6500
    Affected if Device is not a JD Cloud BE6500 router (not affected)
  2. Check installed firmware version
    Log into the router admin panel (typically via http://192.168.1.1 or similar) and navigate to System Settings or Status to view the firmware version, or retrieve it via CLI if SSH/Telnet access is available
    Affected if Firmware version is 4.4.1.r4308 (exact match to affected version)
  3. Verify /jdcapi endpoint is reachable
    From an authorized network position, attempt an HTTP request to http://<router-ip>/jdcapi - the vulnerable function sub_4780 resides at this endpoint
    Affected if The /jdcapi endpoint returns any HTTP response (indicating the service is exposed)
  4. Check for unauthenticated access to ddns_name parameter
    Send a GET or POST request to the /jdcapi endpoint including the ddns_name parameter (e.g., /jdcapi?function=sub_4780&ddns_name=test) - the vulnerability allows injection without authentication
    Affected if The endpoint processes the ddns_name parameter without requiring authentication

If the device is a JD Cloud BE6500 running firmware version 4.4.1.r4308 and the /jdcapi endpoint with the ddns_name parameter is accessible without authentication, the device is affected by CVE-2025-15081.
