Subject [jira] Commented: (DERBY-3532) Invalid & possibly skipped authentication handling when shutting down the network server.
Date Thu, 06 Aug 2009 16:38:14 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740143#action_12740143
] 

Kathey Marsden commented on DERBY-3532:
---------------------------------------

You got the exception org.apache.derby.client.am.SqlException: The URL 'jdbc:derby://localhost:1527/'
is not properly formed
It seems it is missing the shutdown. The url should be getURLBase()  + ";shutdown=true'

The comment is  mysterious because 
1) We do not I think support remote testing with JUnit.
2) If we did, the embedded driver would not be available, just the client, so you wouldn't
be able to shutdown using the embedded driver.

I think it is ok to change

> In NetworkServerControlImpl.checkShutdownPrivileges() code fetches the internal authentication
service to perform user authentication.
> However if no such authentication service is found (null is returned) then authentication
is bypassed, this has the potential of being a security hole.
> The discussion in DERBY-2109 indicated that even with authentication NONE, there is still
an internal authentication service, thus null is not a valid return when getting the internal
authentication service. A secure fail safe system would be to not bypass authentication if
null is returned.
> I tried removing the check for null in the method and that lead to NullPointerExceptions.
This means that something wrong is going on and very possibly no authentication checks are
actually being made when shutting down the network server.
> The null return might be due to checking the authentication after Derby has been shutdown.
