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 SolarWinds Platform was susceptible to the Exposure of Sensitive Information Vulnerability. This vulnerability allows users to access Orion.WebCommunityStrings SWIS schema object and obtain sensitive information.

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 SolarWinds Platform contains an information disclosure vulnerability in its Orion.WebCommunityStrings SWIS (SolarWinds Information Service) schema object. Authenticated or potentially unauthenticated users can access this schema object to retrieve sensitive information that should not be exposed.

MitigationApply the vendor-supplied patch for CVE-2023-23839 when available. In the interim, review and restrict access to the Orion web interface and SWIS schema endpoints to minimize exposure of sensitive data.

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 SolarWinds Platform installation and version
    Locate the SolarWinds Platform installation and retrieve the installed version number. This is typically available through the SolarWinds Orion web console, the SolarWinds Installation Manager, or system information utilities that enumerate installed software.
    Affected if The installed version is below 2023.2.0 (any version in the range below this release is affected).
  2. Confirm Orion web interface accessibility
    Determine whether the SolarWinds Orion web interface is accessible from the network. This can be done by attempting to reach the Orion web URL from an external perspective or reviewing firewall/network access controls that permit or block access to the web interface ports.
    Affected if The Orion web interface is externally accessible or accessible to untrusted users, increasing exposure of the vulnerable schema object.
  3. Verify SWIS schema endpoint exposure
    Identify whether the SolarWinds Information Service (SWIS) schema endpoints, specifically the Orion.WebCommunityStrings object endpoint, are exposed. This may involve reviewing web server configuration, URL access patterns, or attempting to query the schema endpoint if accessible.
    Affected if The SWIS schema endpoint (Orion.WebCommunityStrings) is accessible without additional restrictions, allowing retrieval of the sensitive schema object.
  4. Assess authentication requirements for schema access
    Determine what authentication is required to access the Orion.WebCommunityStrings SWIS schema object. The vulnerability description indicates authenticated or potentially unauthenticated users can access this schema object.
    Affected if The schema object can be accessed with no authentication, minimal authentication, or by users who should not have access to sensitive schema information.

A user is affected if they have SolarWinds Platform installed with a version below 2023.2.0 and the Orion web interface or SWIS schema endpoint is accessible to untrusted or unauthenticated users.

Recommended fix Moderate confidence

SolarWinds Platform 2023.2.0

  1. 1. Review the SolarWinds Platform release notes for version 2023.2.0 to understand new features and any prerequisites.
  2. 2. Ensure you have a current backup of your SolarWinds database and configuration.
  3. 3. Download the SolarWinds Platform 2023.2.0 installer from the official SolarWinds customer portal.
  4. 4. Stop all SolarWinds services or put the system in maintenance mode before upgrading.
  5. 5. Run the installer and follow the upgrade wizard prompts.
  6. 6. After installation, verify all services start correctly.
  7. 7. Validate that the Orion.WebCommunityStrings SWIS schema object is no longer accessible to unauthorized users.
  8. 8. Review user permissions and access controls in SolarWinds to ensure proper security settings.
Caveat Review upgrade prerequisites and compatibility with existing extensions/plugins; test in non-production environment first
