CVE-2021-35225
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 · uneditedEach authenticated Orion Platform user in a MSP (Managed Service Provider) environment can view and browse all NetPath Services from all that MSP's customers. This can lead to any user having a limited insight into other customer's infrastructure and potential data cross-contamination.
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 confidenceThe SolarWinds Orion Platform's NetPath Services component has an access control flaw where authenticated users in MSP (Managed Service Provider) environments can view and browse services from all customers managed by that MSP, rather than being restricted to data within their own customer scope. This allows unauthorized cross-tenant visibility into other customers' infrastructure through the NetPath feature.

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.
-
Identify the installed SolarWinds Network Performance Monitor versionNavigate to the Orion Web Console, then go to Help > About, or check the Windows installed programs list for SolarWinds Network Performance Monitor versionAffected if The installed version is 2020.2.6 or any version lower than 2020.2.6 (any version <= 2020.2.6)
-
Confirm the NetPath feature is enabled and accessibleLog into the Orion Web Console and verify that NetPath is visible and accessible as a feature in the web interface - typically found under the Views or Network sectionAffected if NetPath is enabled and the user has access to the NetPath Services component
-
Verify the environment is configured as an MSP or multitenant setupCheck the Orion Platform configuration for MSP/multitenant settings - this is typically found in the Orion Settings under Account or Administration, or check if multiple customer organizations are defined within the platformAffected if The Orion Platform is configured with multiple customer tenants (MSP configuration) rather than a single organization
-
Review user role assignments and customer scope boundariesIn the Orion Web Console, navigate to the MSP customer organization settings and examine user role assignments to determine if users are assigned to specific customer scopes or if they have broad accessAffected if Users in the environment have authenticated access but the system does not enforce strict customer-specific data boundaries for the NetPath feature
You are affected if your SolarWinds Network Performance Monitor is version 2020.2.6 or lower, NetPath is enabled, and the platform is configured in MSP/multitenant mode where users could potentially see services from customers other than their assigned scope.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper tenant isolation and role-based access controls in the NetPath Services component to enforce customer-specific data boundaries, ensuring users can only access services within their assigned customer scope in MSP environments.
