'Name' => 'Oracle 9i XDB FTP UNLOCK Overflow (win32)',
'Description' => %q{
By passing an overly long token to the UNLOCK command, a
stack based buffer overflow occurs. David Litchfield, has
illustrated multiple vulnerabilities in the Oracle 9i XML
Database (XDB), during a seminar on "Variations in exploit
methods between Linux and Windows" presented at the Blackhat
conference. Oracle9i includes a number of default accounts,
including dbsnmp:dbsmp, scott:tiger, system:manager, and
sys:change_on_install.
