Vulnerable:

$allowhtml = ( isset($HTTP_POST_VARS['allowhtml']) ) ? (
($HTTP_POST_VARS['allowhtml']) ? TRUE : 0 ) : $board_config['allow_html'];
$allowbbcode = ( isset($HTTP_POST_VARS['allowbbcode']) ) ? (
($HTTP_POST_VARS['allowbbcode']) ? TRUE : 0 ) :
$board_config['allow_bbcode'];
$allowsmilies = ( isset($HTTP_POST_VARS['allowsmilies']) ) ? (
($HTTP_POST_VARS['allowsmilies']) ? TRUE : 0 ) :
$board_config['allow_smilies'];

Fixed:

$allowhtml = ( $board_config['allowhtml']) ) ? TRUE : 0;
$allowbbcode = ( $board_config['allowbbcode']) ) ? TRUE : 0;
$allowsmilies = ( $board_config['allowsmilies']) ) ? TRUE : 0;
