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
Command injection vulnerability in the homemng.htm endpoint in Juplink RX4-1500 Wifi router firmware versions V1.0.2, V1.0.3, V1.0.4, and V1.0.5 allows authenticated remote attackers to execute commands as root via specially crafted HTTP requests to the vulnerable endpoint.

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

Command injection vulnerability in the homemng.htm endpoint of Juplink RX4-1500 Wifi routers (firmware V1.0.2-V1.0.5) allows authenticated remote attackers to execute arbitrary commands as root via specially crafted HTTP requests. The vulnerability has a CVSS score of 8.8 (HIGH), indicating significant impact potential.

MitigationPrimary mitigation is applying vendor firmware updates if available. If no patch exists, implement network segmentation to restrict access to the router management interface and disable remote administration where possible.

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 device model
    Access the router web interface or check the device label/marketing materials to confirm the exact model is Juplink RX4-1500
    Affected if Device is not a Juplink RX4-1500 model - this CVE only applies to that specific model
  2. Check firmware version
    Navigate to the router admin interface (typically http://192.168.1.1 or similar) and look for a firmware version indicator in the status or settings pages. Compare the displayed version against 1.0.2, 1.0.3, 1.0.4, or 1.0.5
    Affected if Firmware version matches exactly 1.0.2, 1.0.3, 1.0.4, or 1.0.5 - these are the affected versions
  3. Verify homemng.htm endpoint accessibility
    Attempt to access the homemng.htm page via HTTP request (e.g., GET http://<router-ip>/homemng.htm) from a client on the network. Check if the endpoint responds or requires authentication
    Affected if The homemng.htm endpoint is reachable and responds without being blocked by network segmentation or firewall rules
  4. Check remote management settings
    In the router admin interface, look for settings related to 'Remote Management', 'Remote Access', or 'Admin from WAN'. Verify if remote access is enabled and on which ports
    Affected if Remote management/WAN access to the admin interface is enabled, allowing potential attackers outside the local network to reach the vulnerable endpoint
  5. Confirm authentication status
    Attempt to log into the router admin interface or check if default credentials are in use. The vulnerability requires an authenticated session, so verify if you can obtain valid admin credentials
    Affected if Valid admin credentials are known or guessable, meaning an attacker could potentially authenticate before exploiting the command injection

You are affected if you have a Juplink RX4-1500 router running firmware version 1.0.2, 1.0.3, 1.0.4, or 1.0.5 where the homemng.htm endpoint is accessible and an attacker could obtain authentication credentials.
