edecms中的album_add.php SQL注入漏洞

我看了下该表dede_archives的mtype字段类型是mediumint，于是加了个判断:
221行，找到这个源代码位置:
//保存到主表
$inQuery = "INSERT INTO `#@__archives`(id,typeid,sortrank,flag,ismake,channel,arcrank,click,money,title,shorttitle,
color,writer,source,litpic,pubdate,senddate,mid,description,keywords,mtype)
VALUES ('$arcID','$typeid','$sortrank','$flag','$ismake','$channelid','$arcrank','0','$money','$title','$shorttitle',
'$color','$writer','$source','$litpic','$pubdate','$senddate','$mid','$description','$keywords','$mtypesid'); ";

修改为:
//保存到主表
if(!is_int($mtypesid)) exit();
$inQuery = "INSERT INTO `#@__archives`(id,typeid,sortrank,flag,ismake,channel,arcrank,click,money,title,shorttitle,
color,writer,source,litpic,pubdate,senddate,mid,description,keywords,mtype)
VALUES ('$arcID','$typeid','$sortrank','$flag','$ismake','$channelid','$arcrank','0','$money','$title','$shorttitle',
'$color','$writer','$source','$litpic','$pubdate','$senddate','$mid','$description','$keywords','$mtypesid'); ";
