为了让大家的织梦CMS更安全，有需要的手工在config_base.php里加上
打开
config_base.php
找到
//禁止用户提交某些特殊变量 $ckvs = Array('_GET','_POST','_COOKIE','_FILES'); foreach($ckvs as $ckv){ if(is_array($$ckv)){ foreach($$ckv AS $key => $value) if(eregi("^(cfg_|globals)",$key)) unset(${$ckv}[$key]); } }改为下面代码
//把get、post、cookie里的<? 替换成 <? $ckvs = Array('_GET','_POST','_COOKIE'); foreach($ckvs as $ckv){ if(is_array($$ckv)){ foreach($$ckv AS $key => $value) if(!empty($value)){ ${$ckv}[$key] = str_replace('<'.'?','&'.'lt;'.'?',$value); ${$ckv}[$key] = str_replace('?'.'>','?'.'&'.'gt;',${$ckv}[$key]); 内容来自dedecms } if(eregi("^cfg_|globals",$key)) unset(${$ckv}[$key]); } } //检测上传的文件中是否有PHP代码，有直接退出处理 if (is_array($_FILES)) { foreach($_FILES AS $name => $value){ ${$name} = $value['tmp_name']; $fp = @fopen(${$name},'r'); $fstr = @fread($fp,filesize(${$name})); @fclose($fp); if($fstr!='' && ereg("<\?",$fstr)){ echo "你上传的文件中含有危险内容，程序终止处理！"; exit(); } } }
