> Project: Cassandra
> Issue Type: Improvement
> Reporter: Ya Xiao
> Priority: Normal

> 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 org.apache.cassandra.gms.Gossiper.java, use java.util.Random instead
> of java.security.SecureRandom at Line 123.
> *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?
