安全设置五：任意文件上传漏洞
①、漏洞文件① /include/dialog/select_soft_post.php
$fullfilename = $cfg_basedir.$activepath.'/'.$filename;
修改为
if (preg_match('#.(php|pl|cgi|asp|aspx|jsp|php5|php4|php3|shtm|shtml)[^a-zA-Z0-9]+$#i', trim($filename))) {
ShowMsg("你指定的文件名被系统禁止！",'javascript:;');
exit();
}
$fullfilename = $cfg_basedir.$activepath.'/'.$filename;
|
②、漏洞文件 /dede/media_add.php
这是后台文件任意上传漏洞(上面有说删除此文件，如果不删除，需要使用这个功能，那么修改以下代码补掉漏洞)
$fullfilename = $cfg_basedir.$filename;
修改为
if (preg_match('#.(php|pl|cgi|asp|aspx|jsp|php5|php4|php3|shtm|shtml)[^a-zA-Z0-9]+$#i', trim($filename))) {
ShowMsg("你指定的文件名被系统禁止！",'javascript:;');
exit();
}
$fullfilename = $cfg_basedir.$filename;
|
③、漏洞文件 /include/uploadsafe.inc.php (修改两个地方)
$image_dd = @getimagesize($$_key);
修改为
$image_dd = @getimagesize($$_key); if($image_dd == false){ continue; }
|
${$_key.'_size'} = @filesize($$_key);}
修改为
${$_key.'_size'} = @filesize($$_key);}
$imtypes = array("image/pjpeg", "image/jpeg", "image/gif", "image/png", "image/xpng", "image/wbmp", "image/bmp");
if(in_array(strtolower(trim(${$_key.'_type'})), $imtypes)) { $image_dd = @getimagesize($$_key); if($image_dd == false){ continue; }
if (!is_array($image_dd)) { exit('Upload filetype not allow !');} }
|
安全设置六、SQL注入漏洞
①、漏洞文件 /include/filter.inc.php (大概在46行)
return $svar; 修改为 return addslashes($svar); |
②、漏洞文件 /plus/search.php (大概在109行)
$keyword = addslashes(cn_substr($keyword,30)); 修改为 $typeid = intval($typeid); $keyword = addslashes(cn_substr($keyword,30)); |
③、漏洞文件 /member/mtypes.php (大概在71行)
$query = "UPDATE `dede_mtypes` SET mtypename='$name' WHERE mtypeid='$id' AND mid='$cfg_ml->M_ID'"; 修改为 $id = intval($id); $query = "UPDATE `dede_mtypes` SET mtypename='$name' WHERE mtypeid='$id' AND mid='$cfg_ml->M_ID'"; |
④、漏洞文件 /member/pm.php文件 (大概在65行)
$row = $dsql->GetOne("SELECT * FROM `dede_member_pms` WHERE id='$id' AND (fromid='{$cfg_ml->M_ID}' OR toid='{$cfg_ml->M_ID}')");
修改为
$id = intval($id); $row = $dsql->GetOne("SELECT * FROM `dede_member_pms` WHERE id='$id' AND (fromid='{$cfg_ml->M_ID}' OR toid='{$cfg_ml->M_ID}')");
|
⑤、漏洞文件 /plus/guestbook/edit.inc.php (大概在55行)
$dsql->ExecuteNoneQuery("UPDATE `dede_guestbook` SET `msg`='$msg', `posttime`='".time()."' WHERE id='$id' ");
修改为
$msg = addslashes($msg); $dsql->ExecuteNoneQuery("UPDATE `dede_guestbook` SET `msg`='$msg', `posttime`='".time()."' WHERE id='$id' ");;
|
⑥、漏洞文件 /member/soft_add.php (大概在154行)
$urls .= "{dede:link islocal='1' text='{$servermsg1}'} $softurl1 {/dede:link}
";
修改为
if (preg_match("#}(.*?){/dede:link}{dede:#sim", $servermsg1) != 1)
{ $urls .= "{dede:link islocal='1' text='{$servermsg1}'} $softurl1 {/dede:link}
"; }
|
⑦、漏洞文件 /member/article_add.php (大概在83行,cookies泄漏导致SQL漏洞)
if (empty($dede_fieldshash) || $dede_fieldshash != md5($dede_addonfields.$cfg_cookie_encode)) 修改为 if (empty($dede_fieldshash) || ( $dede_fieldshash != md5($dede_addonfields . $cfg_cookie_encode) && $dede_fieldshash != md5($dede_addonfields . 'anythingelse' . $cfg_cookie_encode))) |
⑧、漏洞文件 /member/album_add.php (大约220行，对输入参数mtypesid未进行int整型转义，导致SQL注入发生)
$description = HtmlReplace($description, -1);//2011.06.30 增加html过滤 （by:织梦的鱼） 修改为 $description = HtmlReplace($description, -1);//2011.06.30 增加html过滤 （by:织梦的鱼） $mtypesid = intval($mtypesid); |
⑨、漏洞文件 /member/inc/inc_archives_functions.php (大概在239行,cookies泄漏导致SQL漏洞)
echo "<input type="hidden" name="dede_fieldshash" value="".md5($dede_addonfields.$cfg_cookie_encode)."" />"; 修改为 echo "<input type="hidden" name="dede_fieldshash" value="". md5($dede_addonfields . 'anythingelse' .$cfg_cookie_encode) ."" />"; |
⑩、漏洞文件 /include/common.inc.php (SESSION变量覆盖导致SQL注入漏洞,最新的版本中已经修复)
if( strlen($svar)>0 && preg_match('#^(cfg_|GLOBALS|_GET|_POST|_COOKIE)#',$svar) )
修改为
if( strlen($svar)>0 && preg_match('#^(cfg_|GLOBALS|_GET|_POST|_COOKIE|_SESSION)#',$svar) )
|
⑪、漏洞文件 /include/payment/alipay.php (支付模块注入漏洞,此漏洞织梦官方在最新的版本中已经修复)
$order_sn = trim($_GET['out_trade_no']); 修改为 $order_sn = trim(addslashes($_GET['out_trade_no'])); |
⑫、漏洞文件 /include/dedesql.class.php (大概在590行)
if(isset($GLOBALS['arrs1'])) 修改为 $arrs1 = array(); $arrs2 = array(); if(isset($GLOBALS['arrs1'])) |
⑬、漏洞文件 /member/inc/archives_check_edit.php (大概第92行，dedecms前台任意文件删除(需要会员中心)，发表文章处，对于编辑文章的时候图片参数处理不当，导致了任意文件删除)
$litpic =$oldlitpic;
修改为
$litpic =$oldlitpic;
if (strpos( $litpic, '..') !== false || strpos( $litpic, $cfg_user_dir."/{$userid}/" ) === false) exit('not allowed path!');
|
安全设置五：无用文件中的风险代码删除
① dede empletslogin_ad.htm（这是织梦默认后台登陆界面的广告代码，没用，删除以下这段代码）
<!--<script type="text/javascript" src="<?php echo UPDATEHOST;?>/dedecms/loginad.<?php echo $cfg_soft_lang; ?>.js"></script>-->
<div class="dede-ad">
<ul>
<script type="text/javascript"src="http://ad.dedecms.com/adsview/?action=single&key=admcploginad&charset=gbk"></script>
</ul>
</div>
|
② dede empletsindex_body.htm（织梦的后台首页模板文件，删除以下这段广告代码）
<iframe name="showad" src="index_body.php?dopost=showad" frameborder="0" width="100%" id="showad" frameborder="0" scrolling="no" marginheight="5"></iframe> |
③ dedemodule_main.php（向织梦官网发送卸载或安装插件的信息，若服务器配置不高，或不支持采集（下载），那会卡死！注释掉以下代码）
SendData($hash);//321行 SendData($hash,2);//527行 |
④ include aglib link.lib.php（织梦官方友链上传的代码，没有用，删除，否则占用性能，甚至卡死）
else if($typeid == 999)
{
}
//将{}里的以及上面的else全部删除
|
⑤ includededemodule.class.php（版本检测代码，30分钟一次，要扫描文件的！为什么管理模块打不开的原因就在这里，网站配置低的，卡死！）
if(file_exists($cachefile) && (filemtime($cachefile) + 60 * 30) > time()) 修改为 if(file_exists($cachefile) && filesize($cachefile) > 10) |
⑥ includededesql.class.php（下面这段代码会给网站加友情链接及版权"Power by DedeCms"，删除）
$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);
$arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72,0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20,0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e);
//特殊操作
$arrs1 = array(); $arrs2 = array(); if(isset($GLOBALS['arrs1']))
{
$v1 = $v2 = '';
for($i=0;isset($arrs1[$i]);$i++)
{
$v1 .= chr($arrs1[$i]);
}
for($i=0;isset($arrs2[$i]);$i++)
{
$v2 .= chr($arrs2[$i]);
}
$GLOBALS[$v1] .= $v2;
}
|
⑦ includecommon.func.php(会给网站加版权的，删除)
$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79); $arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f, 0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72, 0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20, 0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e); |
