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
NetModule NSRW web administration interface executes an OS command constructed with unsanitized user input. A successful exploit could allow an authenticated user to execute arbitrary commands with elevated privileges. This issue affects NSRW: from 4.3.0.0 before 4.3.0.119, from 4.4.0.0 before 4.4.0.118, from 4.6.0.0 before 4.6.0.105, from 4.7.0.0 before 4.7.0.103.

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

NetModule NSRW web administration interface contains an OS command injection vulnerability where user-supplied input is passed to system commands without proper sanitization. An attacker with valid authentication credentials can inject arbitrary OS commands that execute with elevated privileges on the underlying system.

MitigationUpgrade NetModule NSRW firmware to version 4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103 or later. Until patching is feasible, limit web administration interface access to trusted internal networks or specific IP addresses using firewall rules.

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 NetModule Router Software installation
    Locate the NetModule NSRW device or software on your network. The product is typically a NetModule router appliance with web administration interface accessible via HTTP/HTTPS.
    Affected if Device runs NetModule Router Software firmware.
  2. Determine the installed firmware version
    Access the device administrative interface or use SNMP, CLI, or device status page to retrieve the current firmware version. Compare the version number against the affected ranges: 4.3.0.0 to 4.3.0.118, 4.4.0.0 to 4.4.0.117, 4.6.0.0 to 4.6.0.104, or 4.7.0.0 to 4.7.0.102.
    Affected if Installed version falls within any of the four affected version ranges.
  3. Verify web administration interface is enabled
    Check device configuration to confirm the NSRW web administration interface (typically on port 80 or 443) is enabled and accessible.
    Affected if Web administration interface is enabled and reachable.
  4. Assess network accessibility of admin interface
    Determine if the web administration interface is exposed to untrusted networks, the internet, or unauthorized IP addresses by reviewing firewall rules, NAT configurations, or access control lists.
    Affected if Admin interface is accessible from untrusted networks or IP ranges.

You are affected if NetModule Router Software is running with a version in any of the four affected ranges AND the web administration interface is enabled and accessible to the attacker.

Fixed in 4.3.0.1194.4.0.1184.6.0.105
Interim mitigation

Upgrade NetModule NSRW firmware to version 4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103 or later. Until patching is feasible, limit web administration interface access to trusted internal networks or specific IP addresses using firewall rules.

Recommended fix High confidence

4.3.0.119 (for 4.3.x branch), 4.4.0.118 (for 4.4.x branch), 4.6.0.105 (for 4.6.x branch), or 4.7.0.103 (for 4.7.x branch) - recommend upgrading to the latest stable release in the newest branch (4.7.x)

  1. Access the NetModule Router web administration interface or CLI
  2. Locate the firmware update section in the administration panel
  3. Download the appropriate fixed firmware version from NetModule's official support portal (share.netmodule.com or vendor-supplied channels)
  4. Upload the firmware file matching your current version branch (4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103)
  5. Confirm the firmware installation and allow the device to reboot
  6. Verify the new version is installed by checking the system information page
