Authorization Flaw in Apache NiFi Affecting Parameter Contexts and Controller Services

CVE-2024-56512

What is CVE-2024-56512?

CVE-2024-56512 is a significant vulnerability found in the Apache NiFi data integration framework, affecting versions 1.10.0 through 2.0.0. Apache NiFi is designed for automating the flow of data between systems and managing data logistics effectively. This vulnerability allows authenticated users to exploit a lack of fine-grained authorization checks related to Parameter Contexts, Controller Services, and Parameter Providers during the creation of new Process Groups. Organizations leveraging Apache NiFi could face serious issues, as unauthorized access to sensitive or critical Parameter values may compromise data integrity and security.

Technical Details

The vulnerability arises from inadequate authorization validation when users create new Process Groups that bind to Parameter Contexts. In scenarios where no Parameter values are referenced, the system fails to enforce authorization for the associated Parameter Context, allowing unauthorized users to access non-sensitive Parameter values. Additionally, when referenced Controller Services or Parameter Providers are utilized in creating Process Groups, the framework similarly neglects authorization checks, enabling users to interact with components to which they have not been granted access.

Potential impact of CVE-2024-56512

1. Unauthorized Information Access: The vulnerability allows authenticated users to retrieve non-sensitive Parameter values that they would typically not have permission to access, potentially revealing logic or configuration details that could aid malicious actors.

2. Privilege Escalation: By exploiting this vulnerability, users can access and utilize Controller Services or Parameter Providers that should be restricted, leading to unauthorized control over critical data flows and potentially affecting overall system operations.

3. Data Integrity Risks: Since this vulnerability may enable unauthorized manipulation of data flows, the integrity of data processed within the system could be compromised, resulting in incorrect data output or erroneous processing actions that affect business operations.
