前两天应上司的要求对公司某频道做了日志的分析

备注：xxx代表某域名或某信息

一、日志记录分析

漏洞1：文件上传漏洞危险等级：非常严重

通过日志分析，发现黑客在2014年2月22日用http://xxx/css_edit/css.php（后来更改为cssx.php）文件上传漏洞，获取webshell权限，并且在服务器上植入木马程序。

黑客分别在2014年2月27日和2014年3月3日通过木马程序远程操作，植入恶意“时时彩templates_c/templates.php”。

漏洞2：数据库文件暴露危险等级：严重

http://xxx/configuration.php1205

http://xxx/configuration.php140304等

运维人员不正确备份数据文件

二、演示入侵点

入侵点：http://xxx/css_edit/cssx.php

生成文件地址：http://xxx/css_edit/s.php

xxx在2014年3月13加强安全策略禁止大部分php危险函数及限制站点目录，但是此严重漏洞尚未修复，还可以利用。

三、尝试通过黑客留下的木马程序远程连接服务器

获取文件管理权限截图

获取数据库权限截图

并尝试了破解md5

成功破解，密码非常简单

后台地址：http://xxx/administrator

案例：用户名gjy 密码gjy123

四、数据库数据及日志分析

百度收录频道“时时彩”：目前对数据库数据及日志，检索暂无发现“时时彩”恶意数据。

五、安全建议：

1、备份数据，对数据再次过滤一下是存留下恶意代码，对比所有文件找出所有木马或者重新装应用。

2、修复上文所说的漏洞。

3、有可能黑客通过webshell权限提权获取了系统权限，修改系统管理密码。

4、应用后台管理员密码尽量超8位(数字字符特殊字符组成)。
