URL: https://issues.apache.org/jira/browse/FLINK-20996
Project: Flink
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:*
{color:#172b4d}In file
flink/flink-end-to-end-tests/flink-stream-state-ttl-test/src/main/java/org/apache/flink/streaming/tests/verify/AbstractTtlStateVerifier.java{color},
use java.util.Random instead of java.security.SecureRandom at Line 39.
*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.
