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

The Network Configuration Manager contains a directory traversal vulnerability that allows authenticated low-privilege users to escape the intended directory boundaries and execute arbitrary code on the underlying system. Combined with the privilege escalation to SYSTEM-level access, an attacker can gain full control of the affected server.

MitigationImplement strict input validation on all file path parameters to prevent directory traversal sequences (e.g., ../). Apply the principle of least privilege to limit user permissions, and ensure the application runs with minimal necessary privileges rather than SYSTEM-level access.

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 the installed version of Solarwinds Network Configuration Manager
    Locate the NCM installation directory and check the version information, typically found in the application about page, installer files, or registry entries for the Solarwinds product
    Affected if The installed version is any version prior to 2023.4 (for example, 2023.3.x, 2023.2.x, or earlier releases)
  2. Verify if the NCM web interface or API is accessible to authenticated users
    Confirm that the web-based management interface is enabled and accessible, then check which user accounts have valid login credentials
    Affected if Low-privilege authenticated users can access the NCM web interface or API features that handle file operations
  3. Determine the service account privileges for the NCM application
    Check the Windows service properties for the Solarwinds NCM service to identify the logon account, or examine process privileges if the application runs as a standalone process
    Affected if The application service runs under SYSTEM account or another highly privileged account rather than a limited service account
  4. Inspect available file transfer or configuration upload features
    Review the NCM administrative interface for features that allow file uploads, configuration transfers, or file system operations accessible to standard users
    Affected if Authenticated low-privilege users have access to file operation features without additional authorization checks
  5. Examine application logs for directory traversal patterns
    Review NCM log files for entries containing sequences like ../, ..\, or unusual path patterns in file operation requests
    Affected if Logs contain any directory traversal attempt patterns or evidence of unauthorized path access from user accounts

You are affected if your installed Solarwinds Network Configuration Manager version is before 2023.4 and low-privilege authenticated users can access file operation features in the application.

Interim mitigation

Implement strict input validation on all file path parameters to prevent directory traversal sequences (e.g., ../). Apply the principle of least privilege to limit user permissions, and ensure the application runs with minimal necessary privileges rather than SYSTEM-level access.
