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
Nozomi Networks Labs identified a CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in the Administration WebUI in Waterfall WF-500 RX Host in version 7.9.1.0 R2502171040 that allows remote authenticated attackers to execute arbitrary operating system commands on the WF-500 RX Host.

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

CWE-78 OS Command Injection vulnerability in the Administration WebUI of Waterfall WF-500 RX Host version 7.9.1.0 R2502171040 allows remote authenticated attackers to inject and execute arbitrary operating system commands through unsanitized user input in web interface parameters.

MitigationApply vendor patch when available; in interim, restrict administrative access to trusted IP addresses only and implement network segmentation to limit exposure of the WebUI to untrusted networks.

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 WF-500 firmware version
    Access the Administration WebUI and navigate to the System Information or About page to view the firmware version, or use the device CLI command to display version details (e.g., 'show version' or 'system info')
    Affected if The displayed firmware version is 7.9.1.0_r2502171040 or any version prior to it (lower version numbers)
  2. Confirm WebUI is enabled
    Check if the Administration WebUI service is running on the WF-500 device by accessing the web interface via HTTP/HTTPS on the device IP address, or check the device configuration for WebUI enable status
    Affected if The Administration WebUI is accessible and responds to login requests
  3. Verify WebUI network exposure
    Review network configuration to determine if the WebUI is bound to all interfaces or an external-facing network interface, and check firewall or access control lists governing WebUI access
    Affected if The WebUI is accessible from networks beyond the trusted administrative segment
  4. Check WebUI authentication configuration
    Review user accounts and authentication settings within the WF-500 WebUI admin panel to confirm whether default credentials are in use or if weak authentication is configured
    Affected if Default administrative credentials remain unchanged or weak authentication methods are enabled
  5. Identify exploitable web parameters
    Review WebUI functionality for input fields that accept user-supplied data (particularly in administrative configuration sections) that could be passed to underlying system commands
    Affected if The WebUI contains input fields in admin functions where user input is not explicitly validated or sanitized

The environment is affected if the WF-500 firmware version is 7.9.1.0_r2502171040 or lower AND the Administration WebUI is accessible to the attacker (either directly or via network access) with valid authentication credentials.
