CyberRota Analysis
AI-GeneratedApache NiFi versions 2.9.0 through 2.11.0 are vulnerable due to insufficient authorization checks in their Connector configuration update and verification REST API methods, allowing authenticated users to access and apply Secrets and Assets they should not have permission to use. This could lead to unauthorized exposure of sensitive information if an attacker exploits the lack of proper access controls. Organizations using affected versions should prioritize upgrading to 2.12.0 to ensure proper authorization enforcement and mitigate potential security risks.
Original NVD Description
Apache NiFi 2.9.0 through 2.11.0 provide Connector configuration update and verification REST API methods that do not enforce authorization checking on Assets and Secrets referenced in proposed configuration. Updating or verifying a Connector configuration step can apply Asset and Secret references, but framework authorization was limited to write privileges on the Connector itself. As a result of the missing authorization, an authenticated user authorized to modify a Connector, but not authorized to read a referenced Parameter Provider, could apply Secret values backed by that Parameter Provider. The same methods also accepted Asset identifiers without verifying that the Asset belonged to the Connector being configured. Apache NiFi installations that do not implement different levels of authorization across Connectors and Parameter Providers are not subject to this vulnerability, because the framework enforces write permissions on the Connector as the security boundary. Upgrading to Apache NiFi 2.12.0 is the recommended mitigation, which authorizes read access to referenced Parameter Providers and verifies Connector ownership of referenced Assets during configuration update and verification.
