Credit to Author: SSD / Maor Schwartz| Date: Mon, 22 Jan 2018 12:07:17 +0000

漏洞概要以下安全公告描述两个未经身份验证的命令注入漏洞。希捷个人云家庭媒体存储设备是“存储，整理，流式传输，共享所有音乐，电影，照片和重要文档的最简单的方式”。漏洞提交者一位独立的安全研究人员Yorick Koster向 Beyond Security 的 SSD 报告了该漏洞。厂商响应希捷在10月16日被告知该漏洞，虽然已确认收到漏洞信息，但拒绝回应（我们给出的）技术细节，也没有给出确定的修复时间或是协调报告。 CVE：CVE-2018-5347 漏洞详细信息 Seagate Media Server使用Django Web框架并映射到.psp扩展名。任何以.psp结尾的URL都会使用FastCGI协议自动发送到Seagate Media Server应用程序。 /etc/lighttpd/conf.d/django-host.conf: [crayon-5a666358f0897494367467/] URL被映射到文件/usr/lib/django_host/seagate_media_server/urls.py中特定的views。有两个views受到未经认证的命令注入漏洞的影响。受影响的views是： uploadTelemetry getLogs 这些views从GET参数获取用户输入，并将这些未经验证/解析的参数传递给Python模块相应的函数。这允许攻击者注入任意的系统命令，这些命令将以root权限执行。 /usr/lib/django_host/seagate_media_server/views.py： [crayon-5a666358f08a3012049689/] /usr/lib/django_host/seagate_media_server/views.py: [crayon-5a666358f08a8093835846/] 请注意，这两个views都包含csrf_exempt decorator，它会禁用Django的默认开启的CSRF保护。因此，这些问题可以通过跨站请求伪造来进行利用。漏洞证明下面的漏洞验证代码将尝试启用SSH服务，并更改root密码。如果成功，则可以使用新密码通过SSH登录设备。 [crayon-5a666358f08ae242951493/]

For a time, it seemed that it had a shot at becoming the Windows 10 for enterprise because it was seen as a calm port in a storm of radical change.

That hasn’t happened, in part because Microsoft has steered customers away from LTSB.
