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*:
[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:*
