为了让大家的织梦CMS程序更安全,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]);}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();}}}
这样处理之后,安全上理论上可中做到一劳永逸,但缺点是使用此功能后,不能在线上传PHP文件,如果你的站点同时支持asp、aspx等,在此基础上修改一下上述代码即可
