CVE-2024-56512
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 · uneditedApache NiFi 1.10.0 through 2.0.0 are missing fine-grained authorization checking for Parameter Contexts, referenced Controller Services, and referenced Parameter Providers, when creating new Process Groups. Creating a new Process Group can include binding to a Parameter Context, but in cases where the Process Group did not reference any Parameter values, the framework did not check user authorization for the bound Parameter Context. Missing authorization for a bound Parameter Context enabled clients to download non-sensitive Parameter values after creating the Process Group. Creating a new Process Group can also include referencing existing Controller Services or Parameter Providers. The framework did not check user authorization for referenced Controller Services or Parameter Providers, enabling clients to create Process Groups and use these components that were otherwise unauthorized. This vulnerability is limited in scope to authenticated users authorized to create Process Groups. The scope is further limited to deployments with component-based authorization policies. Upgrading to Apache NiFi 2.1.0 is the recommended mitigation, which includes authorization checking for Parameter and Controller Service references on Process Group creation.
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 · high confidenceApache NiFi 1.10.0 through 2.0.0 lack authorization checks when creating new Process Groups that bind to Parameter Contexts, reference Controller Services, or reference Parameter Providers. Authenticated users authorized to create Process Groups could access non-sensitive Parameter values and use unauthorized Controller Services/Parameter Providers by exploiting missing authorization validation during Process Group creation.

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.
-
Verify NiFi version is within affected rangeCheck the installed Apache NiFi version in the UI (top-right corner) or via the /nifi-api/flow/about endpoint. Compare to affected range >= 1.10.0 and < 2.1.0.Affected if Version is 1.10.0 through 2.0.0 inclusive.
-
Confirm Parameter Contexts existIn NiFi UI, navigate to the Parameter Contexts page (hamburger menu > Controller Settings > Parameter Contexts) or query the /nifi-api/parameter-contexts endpoint via API.Affected if One or more Parameter Contexts are configured in the environment.
-
Confirm Controller Services are configuredIn NiFi UI, navigate to the Controller Services page (hamburger menu > Controller Settings > Controller Services) or query the /nifi-api/controller-services endpoint via API.Affected if One or more Controller Services exist in the environment.
-
Check for user ability to create Process GroupsIn NiFi UI, verify if the authenticated user has permissions to create new Process Groups by dragging a new Process Group onto the canvas or using the API to attempt creation.Affected if User is authenticated and authorized to create Process Groups.
Environment is affected if running NiFi version 1.10.0 through 2.0.0 and has Parameter Contexts, Controller Services, or Parameter Providers configured, with users who can create Process Groups.
