             Summary: Using a cryptographically weak Pseudo Random Number Generator (PRNG)
                 Key: NIFI-8147
                 URL: https://issues.apache.org/jira/browse/NIFI-8147
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Ya Xiao


We are a security research team at Virginia Tech. We are doing an empirical study about the usefulness of the existing security vulnerability detection tools. The following is a reported vulnerability by certain tools. We'll so appreciate it if you can give any feedback on it.

*Vulnerability Description:*

In file [nifi/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/GenerateFlowFile.java|https://github.com/apache/nifi/blob/main/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/GenerateFlowFile.java], use java.util.Random instead of java.security.SecureRandom at Line 202.

*Security Impact:*

Java.util.Random is not cryptographically strong and may expose sensitive information to certain types of attacks when used in a security context.

*Useful Resources*:

*Solution we suggest:*

Replace it with SecureRandom

*Please share with us your opinions/comments if there is any:*
