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 checksWork through these to decide whether this CVE applies to you.
-
Confirm SolarWinds Network Configuration Manager is installedLocate the installation through the Windows Programs and Features list, or check for the SolarWinds NCM service in Windows ServicesAffected if The product is present on the system
-
Identify the installed versionCheck the version of SolarWinds Network Configuration Manager through the Windows Programs and Features details, or right-click the NCM application icon and select Properties to view version informationAffected if The version is listed as lower than 2023.3.0 or the version cannot be confirmed as 2023.3.0 or higher
-
Determine if the web console is accessibleVerify whether the NCM web interface is accessible on the network by attempting to reach the URL (typically https://hostname:443 or the configured port)Affected if The web console responds and is reachable from network locations
-
Verify administrative user access existsReview the list of configured administrative accounts in the NCM web console under Administration or User Management settingsAffected if Any administrative accounts are enabled and accessible for the web interface
-
Check for unauthorized access or suspicious activityReview NCM web server logs and Windows security event logs for unusual directory traversal requests or unexpected command execution patterns from web console sessionsAffected if Logs show directory traversal patterns or unexpected commands originating from the web console
You are affected if SolarWinds Network Configuration Manager is installed with a version lower than 2023.3.0 and the web console is accessible to authenticated administrators.
