Loading vulnerability…
Apache NiFi 1.10.0 through 2.0.0 does not perform fine-grained authorization checks for Parameter Contexts, referenced Controller Services, and referenced Parameter Providers when a user creates a Process Group. A user permitted to create Process Groups can bind a Parameter Context without its authorization being checked when the Process Group does not reference Parameter values, allowing download of non-sensitive Parameter values. The user can also reference otherwise unauthorized Controller Services or Parameter Providers.

This repository contains a Python proof-of-concept exploit for CVE-2024-56512, a vulnerability in Apache NiFi that allows unauthorized access to sensitive API endpoints. The main script, 'Apache_NiFi_Exploit.py', prompts the user for a target NiFi URL and then attempts to access several internal API endpoints without authentication. If successful, it extracts and displays sensitive information such as process group details, configuration, user identities, encryption keys, connection data, system logs, flowfile queues, and version/build information. The exploit demonstrates the risk of improperly secured NiFi deployments and highlights the importance of securing API endpoints. The repository also includes a README, LICENSE, and .gitignore, with the exploit logic entirely contained in the Python script.
