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~');
     }
}
