             Summary: Sentry privileges model: Can Sentry take a database privileges away
from a server privileges?
                 Key: SENTRY-2097
                 URL: https://issues.apache.org/jira/browse/SENTRY-2097
             Project: Sentry
          Issue Type: Bug
          Components: Sentry
            Reporter: Sergio Peña
            Priority: Critical


This issue has been allocated:
CVE-2017-15711

>From security@sentry.apache.org:

Assume I have a user |jack| and a group |datateam|. The
user |jack| belongs to group |datateam|.

Use Sentry for authorization.

|create role admin; grant role admin to group datateam; grant all on
server server1 to role admin; |

Now the role |admin| has the following priveleges.

{noformat}
|+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+
| database | table | partition | column | principal_name |
principal_type | privilege | grant_option | grant_time | grantor |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+
| * | | | | admin | ROLE | * | false | 1480985013185000 | -- |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+|
{noformat}

Assume I have this database.

|create database testdb; |

It is successful. User |jack| created a database |testdb|.

Use Sentry to revoke the privileges on |testdb|;

|revoke all on database `testdb` from role admin; |
The priveleges is still the same.

{noformat}
|+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+
| database | table | partition | column | principal_name |
principal_type | privilege | grant_option | grant_time | grantor |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+
| * | | | | admin | ROLE | * | false | 1480985013185000 | -- |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+-------------------+----------+--+|
{noformat}

Shouldn't Sentry take the privileges on database |testdb| away from the
server |server1|?
