Subject [jira] Created: (DERBY-2437) SYSCS_EXPORT_TABLE can be used to overwrite derby files
Date Fri, 09 Mar 2007 18:43:09 GMT
SYSCS_EXPORT_TABLE can be used to overwrite derby files

                 Key: DERBY-2437
                 URL: https://issues.apache.org/jira/browse/DERBY-2437
             Project: Derby
          Issue Type: Bug
          Components: Security
            Reporter: Daniel John Debrunner
            Priority: Critical

here are no controls over which files SYSCS_EXPORT_TABLE can write, thus allowing any user
that has permission to execute the procedure to try and modufy information that they have
no permissions to do.

In a similar fashion to the one described in DERBY-2436 I could overwrite derby.properties
at least leaqding to a dnial of service attack on the next re-boot.
With more time it might be possible to write out a valid properties file which would allow
chaning the authentication, silentaly adding a new user etc.
