-----------------------------
Summary: Improve security of random generator for HS2 cookies
Key: HIVE-17152
URL: https://issues.apache.org/jira/browse/HIVE-17152
Project: Hive
Issue Type: Bug
Reporter: Tao Li
Assignee: Tao Li
The random number generated is used as a secret to append to a sequence and SHA
to implement a CookieSigner. If this is attackable, then it's possible for an
attacker to sign a cookie as if we had. We should fix this and use SecureRandom
as a stronger random function .
HTTPAuthUtils has a similar issue. If that is attackable, an attacker might be
able to create a similar cookie. Paired with the above issue with the
CookieSigner, it could reasonably spoof a HS2 cookie.
