> Key: RANGER-3151

> Project: Ranger
> Issue Type: Improvement
> Components: Ranger
> Reporter: Ya Xiao

> We found a security vulnerability in file
> [ranger/agents-common/src/main/java/org/apache/ranger/plugin/util/PasswordUtils.java|https://github.com/apache/ranger/blob/71e1dd40366c8eb8e9c498b0b5158d85d603af02/agents-common/src/main/java/org/apache/ranger/plugin/util/PasswordUtils.java].
> It allows a hardcoded salt "f77aLYLo" (at Line 54) passed to the PBE
> instantiation (at Line 79).
> *Security Impact*:
> The salt is expected as a random string. A hardcoded salt may compromise
> system security in a way that cannot be easily remedied.

> *Solution we suggest*
> We suggest generating a random default salt by SecureRandom class.
> *Please share with us your opinions/comments if there is any*
> Is the bug report helpful?
