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 Apache MINA SSHD 到 2.19.0 3.0.0-M1 到 3.0.0-M5 版本2.0.0的 sshd-core 中，以某种（假定为罕见）方式实现 SSH 服务器，存在验证绕过。Apache MINA SSHD 是用于客户端和服务器端 SSH 的 Java 库。在库的服务器部分，存在用于执行异步认证的机制。使用 Apache MINA SSHD 实现的服务器必须包含明确的代码才能利用此功能。此功能的实现存在缺陷，可能导致跳过公钥或基于主机的认证中的签名检查，或返回错误的结果。建议用户升级到 Apache MINA SSHD 2.20.0 或 3.0.0-M6，它们修复了逻辑错误，另外禁止将此异步认证机制用于公钥或基于主机的认证方案：如果使用，SSH 会话将会关闭，且服务器将记录一个条目，指示异步认证只能用于密码或键盘交互认证。（CVE-2026-77185）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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

  - 在 Apache MINA SSHD 版本2.0.02.19.0和 3.0.0-M1 到 3.0.0-M5 中，以某種 （假設很少見） 的方式繞過 sshd-core 中的身份驗證，以實作 SSH 伺服器。Apache MINA SSHD 是一個用於用戶端和伺服器端 SSH 的 Java 程式庫。在程式庫的伺服器部分中，存在執行非同步驗證的機制。使用 Apache MINA SSHD 實作的伺服器必須包含明確的程式碼才能使用此功能。此功能的實作有缺陷，可能會導致跳過公開金鑰或主機型驗證中的簽章檢查，或傳回錯誤的結果。建議使用者升級至 Apache MINA SSHD 2.20.0 或 3.0.0-M6，以修正邏輯錯誤，並額外禁止將此非同步驗證機制與公開金鑰或主機型驗證方案搭配使用：如果使用，SSH 工作階段將會關閉，伺服器將記錄一個項目，指出非同步驗證只能與密碼或鍵盤互動式驗證搭配使用。（CVE-2026-77185）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - SSH サーバーを実装する特定の(稀なと考えられる)方法に対する、 2.0.02.19.0 および 3.0.0-M1 から 3.0.0-M5 の Apache MINA SSHD バージョンの sshd-core での認証バイパス。Apache MINA SSHDは、クライアント側とサーバー側のSSH用のJavaライブラリです。ライブラリのサーバー部分に、非同期認証を実行するメカニズムが存在します。Apache MINA SSHDで実装されたサーバーには、この機能を使用するための明示的なコードが含まれている必要があります。この機能の実装に欠陥があり、公開鍵またはホストベースの認証の署名チェックがスキップされたり、誤った結果が返されたりする可能性があります。ユーザーは、論理エラーを修正し、公開鍵またはホストベースの認証スキームを使用したこの非同期認証メカニズムの使用をさらに禁止する Apache MINA SSHD 2.20.0 または 3.0.0-M6 にアップグレードすることが推奨されます:使用された場合、SSH セッションは閉じられ、サーバーは非同期認証がパスワードまたはキーボードインタラクティブ認証でのみ使用できることを示すエントリをログに記録します。(CVE-2026-77185)

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

Note that Nessus has not tested for these issues 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.

  - Authentication bypass in sshd-core in Apache MINA SSHD versions 2.0.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5     for a certain (presumed rare) way to implement an SSH server. Apache MINA SSHD is a Java library for     client- and server-side SSH. In the server part of the library, a mechanism to perform asynchronous     authentication exists. A server implemented with Apache MINA SSHD must contain explicit code to make use     of this feature. The implementation of this feature was flawed and could potentially lead to skipping     checking the signature in public-key or hostbased authentication, or returning a wrong result. Users are     recommended to upgrade to Apache MINA SSHD 2.20.0 or 3.0.0-M6, which fix the logic error and which     additionally forbid the use of this asynchronous authentication mechanism with the public-key or     hostbased authentication schemes: if used, the SSH session will be closed and the server will log an entry     indicating that asynchronous authentication may be used only with password or keyboard-interactive     authentication. (CVE-2026-77185)

Note that Nessus relies on the presence of the package as reported by the vendor.
