為了讓大家的CMS更安全，有需要的手工在config_base.php里加上
打開
config_base.php 
找到

//禁止用戶提交某些特殊變量$ckvs = Array('_GET','_POST','_COOKIE','_FILES');foreach($ckvs as $ckv){  if(is_array($$ckv)){     foreach($$ckv AS $key => $value)       if(eregi("^(cfg_|globals)",$key)) unset(${$ckv}[$key]);  }}

改為下面代碼

//把get、post、cookie里的<? 替換成 <?$ckvs = Array('_GET','_POST','_COOKIE');foreach($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]);  }}//檢測上傳的文件中是否有PHP代碼，有直接退出處理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 "你上傳的文件中含有危險內(nèi)容，程序終止處理！";      exit();  }}}
