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 Network Configuration Manager was susceptible to a Directory Traversal Remote Code Execution Vulnerability This vulnerability allows a low level user to perform the actions with SYSTEM privileges.

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

Network Configuration Manager had a directory traversal vulnerability that allowed authenticated low-privilege users to escape path boundaries and achieve arbitrary file access, ultimately leading to remote code execution with SYSTEM-level privileges.

MitigationApply vendor-supplied patches for CVE-2023-33227 immediately. Until patched, restrict network access to the management interface and audit user privileges to minimize the attack surface.

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. Confirm SolarWinds NCM is installed
    Check for the NCM service or application installation. On Windows, open Services console and look for 'SolarWinds Network Configuration Manager' service, or check Program Files for SolarWinds folder.
    Affected if The service or application is present on the system.
  2. Check installed version
    Access the web management interface and look for the version in the Help > About section, or check the registry key HKLM\SOFTWARE\SolarWinds\NCM\Version (path may vary). Compare the version number to 2023.4.
    Affected if The installed version is any version prior to 2023.4 (e.g., 2023.3.x, earlier releases).
  3. Verify web interface accessibility
    Determine if the NCM web interface is reachable on the network. Check if ports 80/443 or the configured NCM HTTP/HTTPS port are open and listening.
    Affected if The web interface is accessible from the network and the system is running a vulnerable version.
  4. Review for unauthorized file access
    Audit web server logs and file system for unusual access patterns. Look for traversal sequences like '../' in web request logs, or check for unexpected files in system directories.
    Affected if Evidence exists of directory traversal attempts or unauthorized file access on a vulnerable version.

The environment is affected if SolarWinds Network Configuration Manager is installed and the version is below 2023.4 with the web interface network-accessible.
