注入链接：/virtual-office/brand.php
注入参数：data[brand]
漏洞代码：（第24行开始）
if (isset($_POST['save']) && !empty($company_id)) {
$company->newCheckStatus($companyinfo['status']);
if(!empty($_POST['data']['brand'])){
$vals = $_POST['data']['brand'];
if(isset($_POST['id'])){
	$id = intval($_POST['id']);
}
$attachment->rename_file = "brand-".($brand->getMaxId()+1);
if(!empty($id)){
	$attachment->insert_new = false;
	$attachment->rename_file = "brand-".$id;
}
if (!empty($_FILES['pic']['name'])) {
	$attachment->upload_process();
	$vals['picture'] = $attachment->file_full_url;
}
if (!empty($vals['description'])) {
	$vals['description'] = stripcslashes($vals['description']);
}
$vals['letter'] = L10n::getinitial($vals['name']);
$vals['member_id'] = $the_memberid;
$vals['company_id'] = $company_id;
if (!empty($id)) {
	$vals['modified'] = $time_stamp;
	$res = $brand->save($vals, "update", $id, null, $conditions);
$vals = $_POST['data']['brand'];从data['brand']中获取job数组参数，并将$vals数组传入save函数，save函数中通过以下以下代码构造SQL语句：(libraries/core/model.php)
$keys = array_keys($posts);
$cols = implode($keys,",");
$tbname = (is_null($tbname))? $this->getTable():trim($tbname);
$this->table_name = $tbname;
if(!empty($id)){
	$sql = "SELECT $cols FROM ".$tbname." WHERE ".$this->primaryKey."='".$id."'";
在save函数中$vals数组的键名会被拆分为select语句的列名列表$cols,由于$vals可控导致sql注入，且是数组键名，因此可绕过代码中的注入检测
