Sql injection in SMF [Admin section]

["Omid" <omid () hackers ir>]

Hi,
There is a sql injection in SMF 1.1 RC3, in admin section :
When an administrator is going to add a new board, the "cur_cat" parameter
is not checked properly :

File /Sources/ManageBoards.php, Line 609 :
:: // Create a new board...
:: if (isset($_POST['add']))
:: {
::      // New boards by default go to the bottom of the category.
::      if (empty($_POST['new_cat']))
> >              $boardOptions['target_category'] = $_POST['cur_cat'];
::      if (!isset($boardOptions['move_to']))
::              $boardOptions['move_to'] = 'bottom';
:: 
> >      createBoard($boardOptions);
:: }

And in "createBoard()" function :

File /Sources/Subs-Boards.php, Line 1095 :
:: // Insert a board, the settings are dealt with later.
:: db_query("
::      INSERT INTO {$db_prefix}boards
::              (ID_CAT, name, description, boardOrder, memberGroups)
> >      VALUES ($boardOptions[target_category], SUBSTRING('$boardOptions[board_name]', 1, 255), '', 0, '-1,0')", 
> > __FILE__, __LINE__);

This is in administration section, so it doesnt seem to be critical.
