dedecms过滤逻辑不严导致上传漏洞。路径：/include/uploadsafe.inc.php，此文件有两个地方需要修改，

搜索

${$_key.'_size'} = @filesize($$_key);      }

(大概在42,43行左右)替换成

          ${$_key.'_size'} = @filesize($$_key);

       } $imtypes = array("image/pjpeg", "image/jpeg", "image/gif", "image/png", "image/xpng", "image/wbmp", "image/bmp"); if(in_array(strtolower(trim(${$_key.'_type'})), $imtypes)) { $image_dd = @getimagesize($$_key); if($image_dd == false){ continue; } if (!is_array($image_dd)) { exit('Upload filetype not allow !'); } }

搜索

$image_dd = @getimagesize($$_key);

(大概在53行左右)替换成

$image_dd = @getimagesize($$_key); if($image_dd == false){ continue; }
