[jira] [Comment Edited] (DERBY-6636) The public api of
BaseDataFileFactory may allow blackhats to assume elevated privileges.

A call to addAndLoadStreamContainer gets frustrated quickly because it need to boot to have been performed before it can success. Result:
{code}
Exception in thread "main" java.lang.NullPointerException

> Key: DERBY-6636
> URL: https://issues.apache.org/jira/browse/DERBY-6636
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.11.0.0
> Reporter: Rick Hillegas
>
> BaseDataFileFactory has a public constructor and a public boot() method. Arbitrary code running in the JVM may be able to instantiate a BaseDataFileFactory outside of Derby's authentication mechanisms and so acquire the ability to read/update Derby-managed data with the privileges granted to Derby. Arbitrary code may be able to interfere with the normal operation of Derby and may be able to corrupt data.
> This is just an observation based on casual code inspection. It may be that there are mechanisms in place which frustrate these attacks. I have not tried to exploit these potential vulnerabilities myself.
