Linux Distros 未修补的漏洞：CVE-2025-30156
high Nessus 插件 ID 338279
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- Ceph 是一个开源分布式存储平台，提供对象、区块和文件存储。在 和 19.2.6之前20.2.4的版本中，CephX 身份验证协议在未经身份验证的模式下使用 AES-128-CBC 加密票证，该模式使用硬编码初始化矢量且无消息身份验证，从而允许攻击者伪造凭据并获得集群范围的访问权限。由于密文可延展，并且监控器将加密攻击者选择的实体名称，因此，持有一个低权限密钥且能够观察 CephX 流量的攻击者可将监控器用作加密预言机，并将密文块拼接成特权实体（例如 Manager、MDS 和 OSD）的有效票证。同样缺少身份验证也会让拥有 CephX 权限的攻击者通过翻转服务票证中的单一位，将其allow_all字段设置为 true，从而提升权限。此问题已在 20.2.4 和 19.2.6 版本中得到修补。(CVE-2025-30156)
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
