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

Severity: medium (CVSS 4.9 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.7% probability of exploitation in the next 30 days
Public exploit or detection template: none known

Weakness: CWE-532

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.

Affected products

Apache Software Foundation Apache NiFi: from 1.16.0 before 1.28.1; 2.0.0-milestone1, 2.0.0-milestone1-rc1, 2.0.0-milestone1-rc2, 2.0.0-milestone1-rc3, 2.0.0-milestone1-rc4, 2.0.0-milestone1-rc5 (+10) — fixed in 1.28.1

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache NiFi 1.28.1. Check the vendor advisory for mitigations.
