> If you have write access to the directory containing a Derby database, then the following easy exploit will let you change the contents of the database and possibly evade detection for some time:
> 1) Create a vacuous dummy database with this ij command:
>      connect 'jdbc:derby:dummydb;create=true';
> 2) Copy the properties conglomerate (c10.dat) from the target database to a side location.
> 3) Now copy the vacuous c10.dat from dummydb into the seg0 directory of the target database.
> 4) Now connect to the target database with the following ij command and change anything you want:
>      connect 'jdbc:derby:targetdb';
> 5) When you are done, copy c10.dat from the side location back into the seg0 directory of the target database.
> I do not regard this as a new vulnerability. That is because once you have write access to a Derby database directory, you have unlimited power to change and corrupt the database. However, I am filing this JIRA so that we will have a name for this particular easy exploit.
