遠端 Ubuntu 22.04 LTS 主機上安裝的套件受到 USN-7926-1 公告中所提及的多個弱點影響。

    Kay 發現OpenStack Keystone 未正確處理 ec2tokens 和 s3tokens API。遠端攻擊者可能利用此問題取得未經授權的存取權並提升權限。
    (CVE-2025-65073)

    據發現OpenStack Keystone 僅驗證應用程式密碼的前 72 個位元組。攻擊者可能利用此問題繞過複雜的密碼。 (CVE-2021-3563)

    據發現OpenStack Keystone 在應透過安全性原則撤銷 token 之前會有時間延遲。遠端系統管理員可利用此問題維持存取權的時間比預期的時間更長。
    (CVE-2022-2447)

Tenable 已直接從 Ubuntu 安全公告擷取前置描述區塊。

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

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。

  - 在 Keystone 中发现一个缺陷。安全策略指示应撤消标记与实际撤消标记之间存在时间差（在默认配置中最多一个小时）。这可允许远程管理员秘密维持访问权限比预期更久。 (CVE-2022-2447)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

远程 Ubuntu 22.04 LTS 主机上安装的多个程序包受到 USN-7926-1 公告中提及的多个漏洞影响。

    Kay 发现 OpenStack Keystone 未能正确处理 ec2tokens 和 s3tokens API。远程攻击者可能利用此问题获得未经授权的访问权限并提升权限。
    (CVE-2025-65073)

    发现 OpenStack Keystone 只验证应用程序密码的前 72 字节。攻击者可能利用此问题绕过密码复杂性。 (CVE-2021-3563)

    发现 OpenStack Keystone 在安全策略撤消标记前存在时间延迟。远程管理员可能利用此问题保持访问权限的时间比预期长。
    (CVE-2022-2447)

Tenable 已直接从 Ubuntu 安全公告中提取上述描述块。

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 Keystone 中發現一個瑕疵。從安全性原則指示應撤銷權杖到實際撤銷權杖之間有一個時間延遲 (預設組態中長達一小時)。這可允許遠端系統管理員以秘密方式維持存取權比預期更長的時間。 (CVE-2022-2447)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - Keystone に欠陥が見つかりました。セキュリティポリシーでトークンを取り消すように指示されてから、実際に取り消されるまでには、時間差 (デフォルト構成では最大 1 時間) があります。これにより、リモートの管理者が予想よりも長い間、密かにアクセスを維持する可能性があります。 （CVE-2022-2447）

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0055 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2022-2447:
    A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when     security policy says a token should be revoked from when it is actually revoked. This could allow a remote     administrator to secretly maintain access for longer than expected.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7926-1 advisory.

    Kay discovered that OpenStack Keystone incorrectly handled the ec2tokens and s3tokens APIs. A remote     attacker could possibly use this issue to obtain unauthorized access and escalate privileges.
    (CVE-2025-65073)

    It was discovered that OpenStack Keystone only validated the first 72 bytes of an application secret. An     attacker could possibly use this issue to bypass password complexity. (CVE-2021-3563)

    It was discovered that OpenStack Keystone had a time lag before a token should be revoked by the security     policy. A remote administrator could use this issue to maintain access for longer than expected.
