[ https://issues.apache.org/jira/browse/SENTRY-1034?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sravya Tirukkovalur updated SENTRY-1034:
----------------------------------------
Summary: Fix beeline connecting to db (was: Security leak in beeline connect command)
> Fix beeline connecting to db
> ----------------------------
>
> Key: SENTRY-1034
> URL: https://issues.apache.org/jira/browse/SENTRY-1034
> Project: Sentry
> Issue Type: Bug
> Components: Core
> Reporter: Istvan Vajnorak
>
> A possible info leak in the way how beeline connects to databases and uses the ACLs to prevent seeing unauthorised databases and tables.
> It turns out that one can connect to a database that one should not see, but listing it afterwards gives no tables. This is still somewhat a security breach as an attacker can gain insight what databases exist.
> The way the problem got identified:
> root@prod-vm-cdh-mgr-01 ~]# kinit -kt ~/allianz_mval.keytab allianz_mval
> [root@prod-vm-cdh-mgr-01 ~]# beeline
> Beeline version 1.1.0-cdh5.4.8 by Apache Hive
> beeline> !connect jdbc:hive2://vm-cdh-01:10000/sriveradb;principal=hive/_HOST@MITKDC
> scan complete in 6ms
