CVE-2024-56512 Scanner

Apache NiFi is a powerful dataflow management tool that is widely used to automate the movement of data between disparate systems. It is employed by organizations for data ingestion, data analytics, and data transfer tasks. Operating as an open-source project, it provides users with a user-friendly interface for designing and managing complex data flows. The software is used across various industries including healthcare, finance, and telecommunications due to its ability to handle large volumes of data efficiently. Developed under the Apache Software Foundation, NiFi's extensible architecture and the ability to operate seamlessly across cloud and on-premise environments make it versatile for meeting diverse data integration needs. Its integration capabilities allow the connection of a variety of data sources and systems, enabling streamlined data processing and governance.

The Information Disclosure vulnerability in Apache NiFi arises from inadequate authorization checks for Parameter Contexts, referenced Controller Services, and Parameter Providers when creating new Process Groups. This flaw allows unauthorized parameter access, compromising system data privacy. Often unnoticed during standard operations, this vulnerability allows users to access non-sensitive parameters without appropriate permissions. It can lead to unauthorized information access where sensitive details remain inadequately protected. Effectively, clients can exploit this behavior to capture data they are not privileged to view, posing significant risks to data integrity and security. This overlooked parameter linkage flaw can serve as a catalyst for further security breaches within an organization’s infrastructure.

Technical details highlight that the vulnerability exploits missing fine-grained authorization checking within certain parts of NiFi's API. Specifically, when creating a Process Group, the failure to authenticate users for bound Parameter Contexts allows unintended data exposure. Vulnerable endpoints include '/nifi-api/flow/process-groups/root' and '/nifi-api/controller/config'. The software does not adequately validate whether a user has proper permissions to bind and access certain parameter contexts during these interactions. If a Process Group doesn’t reference parameter values directly, this oversight can lead to disclosures of unauthorized data. Essentially, the vulnerability allows malicious parties to bypass intended security checks and extract sensitive process flow information via authorized yet unchecked HTTP requests.

Possible effects of exploiting this vulnerability include unauthorized access to configuration data which might be sensitive. Attackers could leverage these unauthorized insights to conduct further targeted attacks within the affected system. Additionally, the exposure of internal configuration components can assist in network mapping for malicious purposes. Unmitigated, this creates potential pathways for expanded intrusions, unauthorized data manipulations, and breaches that compromise data integrity and confidentiality. Furthermore, sustained exploitation may lead to subtle yet damaging changes to configurations that disrupt system operations over time.
