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
The NetModule NSRW web administration interface is vulnerable to path traversals, which could lead to arbitrary file uploads and deletion. By uploading malicious files to the web root directory, authenticated users could gain remote command execution 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 · high confidence

The NetModule NSRW web administration interface contains path traversal vulnerabilities in its file upload functionality. Authenticated users can manipulate file paths to upload malicious files to arbitrary directories, including the web root, enabling remote command execution with elevated privileges.

MitigationUpdate NetModule NSRW firmware to version 4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103 or later. Restrict administrative access to trusted users only until patches are applied.

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 version
    Access the device web administration interface and navigate to System > Status or check the firmware version through the admin panel. Alternatively, check the device documentation for CLI commands to retrieve the firmware version.
    Affected if Version falls within 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
  2. Confirm web administration interface is enabled
    Verify that the NSRW web interface is accessible on the device. Check if HTTP/HTTPS ports for the admin panel are open and responding.
    Affected if The web administration interface is exposed and reachable on the network
  3. Verify admin user access exists
    Check if any administrative accounts are configured on the device. Determine if authentication to the web interface is possible.
    Affected if Administrative credentials exist or can be obtained for the web interface
  4. Confirm file upload functionality is accessible
    Log into the web admin panel and navigate to sections that allow file uploads, such as firmware updates, configuration import, or certificate management.
    Affected if File upload features are available to authenticated users

Environment is affected if the installed NetModule Router Software version is within the affected ranges and the web administration interface with file upload capability is accessible to an authenticated user.

Interim mitigation

Update NetModule NSRW firmware to version 4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103 or later. Restrict administrative access to trusted users only until patches are applied.

Recommended fix High confidence

NetModule Router Software 4.3.0.119, 4.4.0.118, 4.6.0.105, or 4.7.0.103 (or later respective releases) depending on the current version branch

  1. 1. Identify the current NetModule Router Software version installed on the affected device via the web administration interface or CLI.
  2. 2. Determine which version branch (4.3.x, 4.4.x, 4.6.x, or 4.7.x) is currently in use.
  3. 3. Download the appropriate fixed firmware version from NetModule's official support portal or authorized distribution channel:
  4. - For 4.3.x branch: upgrade to version 4.3.0.119 or later
  5. - For 4.4.x branch: upgrade to version 4.4.0.118 or later
  6. - For 4.6.x branch: upgrade to version 4.6.0.105 or later
  7. - For 4.7.x branch: upgrade to version 4.7.0.103 or later
  8. 4. Review NetModule's upgrade documentation for proper firmware update procedures.
