----------------------------
Resolution: Not A Problem
> 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
> Priority: Major
>
> 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*:
> [https://cwe.mitre.org/data/definitions/338.html]
> *Solution we suggest:*
> Replace it with SecureRandom
> *Please share with us your opinions/comments if there is any:*
> Is the bug report helpful?
