There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with
    RabbitMQ nodes. Prior to 5.33.0, com.rabbitmq.client.ConnectionFactory.useSslProtocol() and
    ConnectionFactory.useSslProtocol(String) configure com.rabbitmq.client.TrustEverythingTrustManager and
    leave hostname verification disabled, causing arbitrary server certificates, including self-signed
    certificates, to be accepted. A network attacker able to intercept a TLS connection can impersonate the
    RabbitMQ broker, read protected AMQP traffic, and modify traffic without certificate or hostname
    validation. The fix changes the production TLS helpers to use the JVM default trust store and enables
    hostname verification, while retaining an explicitly named development-only no-verification helper. This
    issue is fixed in version 5.33.0. (CVE-2026-63336)

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。

  - RabbitMQ Java 用戶端程式庫可讓 Java 及 JVM 型應用程式連線至 RabbitMQ 節點並與之互動。在 5.33.0之前，com.rabbitmq.client.ConnectionFactory.useSslProtocol（） 和 ConnectionFactory.useSslProtocol（String） 會設定 com.rabbitmq.client.TrustEverythingTrustManager，並停用主機名稱驗證，導致接受任意伺服器憑證 （包括自我簽署憑證）。能夠攔截 TLS 連線的網路攻擊者可以模擬 RabbitMQ 代理程式、讀取受保護的 AMQP 流量，以及在沒有憑證或主機名稱驗證的情況下修改流量。此修正會將生產 TLS 協助程式變更為使用 JVM 預設信任存放區，並啟用主機名稱驗證，同時保留明確命名的僅限開發的無驗證協助程式。5.33.0 版已修正此問題。(CVE-2026-63336)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - RabbitMQ Java 客户端库允许基于 Java 和 JVM 的应用程序连接到 RabbitMQ 节点并与之交互。在版本 5.33.0com.rabbitmq.client.ConnectionFactory.useSslProtocol（） 和 ConnectionFactory.useSslProtocol（String） 之前，会配置 com.rabbitmq.client.TrustEverythingTrustManager 并禁用主机名验证，从而导致接受任意服务器证书，包括自签名证书。可拦截 TLS 连接的网络攻击者可冒充 RabbitMQ 代理、读取受保护的 AMQP 流量并修改流量而无需验证证书或主机名。此修复将生产 TLS 帮助程序更改为使用 JVM 默认信任存储并启用主机名验证，同时保留明确命名的仅限开发的无验证帮助程序。此问题已在 5.33.0 版本中修复。(CVE-2026-63336)

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 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。

  - RabbitMQ Java クライアント・ライブラリを使用すると、Java および JVM ベースのアプリケーションを RabbitMQ ノードに接続して対話できます。5.33.0の前に、com.rabbitmq.client.ConnectionFactory.useSslProtocol() と ConnectionFactory.useSslProtocol(String) が com.rabbitmq.client.TrustEverythingTrustManager を構成し、ホスト名の検証を無効のままにすることで、自己署名証明書を含む任意のサーバー証明書が受け入れられます。TLS接続を傍受できるネットワーク攻撃者が、RabbitMQブローカーになりすまし、保護されたAMQPトラフィックを読み取ったり、証明書やホスト名を検証せずにトラフィックを変更したりする可能性があります。この修正は、実稼働TLSヘルパーがJVMのデフォルトトラストストアを使用するように変更され、ホスト名の検証を有効にしますが、明示的に名前が付けられた開発専用の検証なしヘルパーは維持されています。この問題はバージョン 5.33.0 で修正されています。(CVE-2026-63336)

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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142337 advisory.

    The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with     RabbitMQ nodes. Prior to 5.33.0, com.rabbitmq.client.ConnectionFactory.useSslProtocol() and     ConnectionFactory.useSslProtocol(String) configure com.rabbitmq.client.TrustEverythingTrustManager and     leave hostname verification disabled, causing arbitrary server certificates, including self-signed     certificates, to be accepted. A network attacker able to intercept a TLS connection can impersonate the     RabbitMQ broker, read protected AMQP traffic, and modify traffic without certificate or hostname     validation. The fix changes the production TLS helpers to use the JVM default trust store and enables     hostname verification, while retaining an explicitly named development-only no-verification helper. This     issue is fixed in version 5.33.0.

Tenable has extracted the preceding description block directly from the Unity 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.
