CVE-2024-52067: Apache NiFi: Potential Insertion of Sensitive Parameter Values in Debug Log

[David Handermann <exceptionfactory () apache org>]

Affected versions:

- Apache NiFi 1.16.0 through 1.28.0
- Apache NiFi 2.0.0-M1 through 2.0.0-M4

Description:

Apache NiFi 1.16.0 through 1.28.0 and 2.0.0-M1 through 2.0.0-M4 include optional debug logging of Parameter Context 
values during the flow synchronization process. An authorized administrator with access to change logging levels could 
enable debug logging for framework flow synchronization, causing the application to write Parameter names and values to 
the application log. Parameter Context values may contain sensitive information depending on application flow 
configuration. Deployments of Apache NiFi with the default Logback configuration do not log Parameter Context values. 
Upgrading to Apache NiFi 2.0.0 or 1.28.1 is the recommendation mitigation, eliminating Parameter value logging from the 
flow synchronization process regardless of the Logback configuration.

This issue is being tracked as NIFI-13971
