简要描述：

由于没有一个通用标准的防御规则保护好中间件配置信息、DNS信息、业务数据信息、用户信息、源码备份文件、版本管理工具信息、系统错误信息和敏感地址信息(后台或测试地址)的泄露，攻击者可能会通过收集这些保护不足的数据，利用这些信息对系统实施进一步的攻击。

详细说明：

#1 信息泄露原因
由于木蚂蚁论坛管理员在更新服务器文件时，未注意到编辑器会默认创建各种.bak文件用来规避错误编辑时引发的数据丢失风险，从而造成了更严重的信息安全问题。
同时使用了第三方数据库管理软件时，未能安全的隐藏路径，导致各种信息泄露被骇客组合，从而利用这些信息对系统实施攻击。
#2 泄露内容
网站：http://bbs.mumayi.com
泄露文件：http://bbs.mumayi.com/config/config_global.php.bak
PHPMYADMIN地址泄露：http://bbs.mumayi.com/{domain_name}phpmyadmin/

漏洞证明：

#3 风险利用
通过泄露的信息，结合PHPMYADMIN，刚好可访问到木蚂蚁的用户数据信息！

{没办法得到SHELL的风险都不算漏洞，测试后已删除}

修复方案：

#1 网络边界需要认真对待。
#2 杜绝为了方便而造成的不必要的信息泄露。
#3 安全是一个整体，保证安全不在于强大的地方有多强大，而在于真正薄弱的地方在哪里。
