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
In N2W before 4.3.2 and 4.4.x before 4.4.1, there is potential remote code execution and account credentials theft because of a spoofing vulnerability.

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

A spoofing vulnerability in N2W software before versions 4.3.2 and 4.4.1 allows attackers to bypass authentication mechanisms, potentially enabling remote code execution and theft of account credentials.

MitigationUpgrade N2W to version 4.3.2 or 4.4.1 or later to remediate the vulnerability.

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 N2W installation version
    Access the N2W administrative interface or check the product About/Version page in the management console. If using CLI, run: n2w --version or check the software package metadata.
    Affected if The installed version is below 4.3.2 or exactly 4.4.0
  2. Confirm N2W is the affected product
    Verify the product name is N2WS (N2w) Backup and Recovery product. This vulnerability specifically affects the N2WS software, not other N2 or backup products.
    Affected if The product is N2WS Backup and Recovery version 4.3.2 or earlier, or version 4.4.0
  3. Check network exposure
    Determine if the N2W web interface or API is exposed to untrusted networks (directly to internet or less trusted internal segments). Review firewall rules and access control lists.
    Affected if The N2W management interface is accessible from untrusted networks without proper network segmentation
  4. Review authentication logs
    Examine N2W authentication and audit logs for unusual login events, failed authentication attempts followed by successful ones from unexpected IPs, or account credential usage anomalies.
    Affected if Logs show successful authentications from unknown source IPs or patterns inconsistent with normal administrative access

A user is affected if N2WS version is below 4.3.2 or exactly 4.4.0 and the management interface is network-accessible.

Upgrade available Upgrade to 4.3.2 or later
Fixed in 4.3.2
Interim mitigation

Upgrade N2W to version 4.3.2 or 4.4.1 or later to remediate the vulnerability.

Recommended fix High confidence

Upgrade to N2W version 4.3.2 (for pre-4.3.2 installs) or version 4.4.1 (for 4.4.0 installs)

  1. 1. Identify the current installed version of N2W by accessing the product interface or checking system information.
  2. 2. If running a version prior to 4.3.2, plan upgrade to version 4.3.2.
  3. 3. If running version 4.4.0, plan upgrade to version 4.4.1.
  4. 4. Review upgrade documentation from official N2W sources (n2ws.com, n2ws.zendesk.com) for upgrade prerequisites.
  5. 5. Perform a backup of current configuration and data before upgrading.
  6. 6. Execute the upgrade process following N2W's standard upgrade procedure.
  7. 7. After upgrade, verify the new version is correctly installed and the web interface is accessible.
  8. 8. Validate that the authentication mechanism is functioning properly and the spoofing vulnerability is resolved.
