遠端 Debian 9 主機上安裝的一個套件受到 dla-2755 公告中提及的一個弱點影響。

  - Btrbk 0.31.2 之前版本允許命令執行，這是因為遠端主機篩選 authorized_keys 中使用 ssh_filter_btrbk.sh 的 SSH 命令時處理不當。(CVE-2021-38173)

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

远程主机受到 GLSA-202402-32 中所述漏洞的影响（btrbk：远程代码执行）

  - 0.31.2 之前的 Btrbk 允许命令执行，这是因为使用 authorized_keys 中的 ssh_filter_btrbk.sh 未正确处理远程主机过滤 SSH 命令。(CVE-2021-38173)

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

远程 Debian 9 主机上安装的一个程序包受到 dla-2755 公告中提及的一个漏洞影响。

リモートのDebian 9ホストには、dla-2755のアドバイザリに記載された脆弱性の影響を受けるパッケージがインストールされています。

   -0.31.2より前のBtrbkでは、authorized_keysのssh_filter_btrbk.shを使用するSSHコマンドをフィルタリングするリモートホストが不適切に処理されるため、コマンドの実行が可能です。（CVE-2021-38173）

Nessusはこの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。

The remote host is affected by the vulnerability described in GLSA-202402-32 (btrbk: Remote Code Execution)

  - Btrbk before 0.31.2 allows command execution because of the mishandling of remote hosts filtering SSH     commands using ssh_filter_btrbk.sh in authorized_keys. (CVE-2021-38173)

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

The remote Debian 9 host has a package installed that is affected by a vulnerability as referenced in the dla-2755 advisory.

    An issue has been found in btrbk, a backup tool for btrfs subvolumes. Due to mishandling of remote hosts     filtering SSH commands using ssh_filter_btrbk.sh in authorized_keys an arbitrary code execution would have     been allowed. For Debian 9 stretch, this problem has been fixed in version 0.24.0-1+deb9u1. We recommend     that you upgrade your btrbk packages. For the detailed security status of btrbk please refer to its     security tracker page at: https://security-tracker.debian.org/tracker/btrbk Further information about     Debian LTS security advisories, how to apply these updates to your system and frequently asked questions     can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian 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 remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-9049-1 advisory.

    It was discovered that btrbk incorrectly filtered SSH commands received from remote hosts. A remote     attacker could possibly use this issue to execute arbitrary commands.

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