Oracle 9i XDB FTP UNLOCK Overflow (win32)
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.
