How to fix?

Upgrade org.apache.nifi:nifi-security-utils to version 1.14.0 or higher.

Overview

org.apache.nifi:nifi-security-utils is a system to process and distribute data.

Affected versions of this package are vulnerable to Cryptographic Issues. NiFi accepts a password and encryption algorithm in {{nifi.properties}} which are used to encrypt all sensitive processor properties throughout the application. The password defaults to empty and the algorithm defaults to {{PBEWITHMD5AND256BITAES-CBC-OPENSSL}}. This algorithm:

  • uses a digest function ({{MD5}}) which is not cryptographically secure [1][2][3][4]
  • uses a single iteration count [5][6]
  • limits password input to 16 characters on JVMs without the unlimited strength cryptographic jurisdiction policy files installed [NIFI-1255]

This is considered insecure practice.
