由于过滤不严，存在多个跨站漏洞

PS:
http://www.blackunion.cn/?viewmode=list&curl=>">alert(blackunion)%3B
http://www.blackunion.cn/?action=index&cid=>">alert(blackunion)%3B
http://www.blackunion.cn/?action=index&setdate=200804&setday=>">alert(blackunion)%3B&page=1

临时解决办法：

在global.php中过滤curl，cid，setday等 $modelink = '';
if ($action) {
$modelink .= '&action='.$action;
}
if ($curl) {
$modelink .= '&curl='.htmlspecialchars($curl);
}
if ($cid) {
$modelink .= '&cid='.htmlspecialchars($cid);
}
if ($setdate) {
$modelink .= '&setdate='.htmlspecialchars($setdate);
}
if ($setday) {
$modelink .= '&setday='.htmlspecialchars($setday);
}
if (intval($_GET['searchid'])) {
$modelink .= '&searchid='.htmlspecialchars($_GET['searchid']);
}
if (intval($_GET['userid'])) {
$modelink .= "&userid=".htmlspecialchars($_GET['userid']);
}
if ($_GET['item']) {
$item = urlencode(addslashes($item));
$modelink .= '&item='.$item;
}

如何最大程度的利用,化被动为主动 正是XSS的乐趣
