リモートの openSUSE 15 ホストには、openSUSE-SU-2024:0008-1 のアドバイザリに記載されている複数の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。

  - 9.6 以前の OpenSSH およびその他の製品の SSH トランスポートプロトコルでは、特定の OpenSSH 拡張機能を使用しています。これにより、リモート攻撃者が整合性チェックを回避し、一部のパケットが (拡張ネゴシエーションメッセージから) 省略される可能性があります。その結果、クライアントとサーバーは一部のセキュリティ機能が低下または無効化された接続になる可能性があり、これは Terrapin 攻撃とも呼ばれます。これは、これらの拡張機能によって実装されている SSH バイナリパケットプロトコル (BPP) が、ハンドシェイクフェーズと、シーケンス番号の使用を不適切に処理するために発生します。たとえば、SSH による ChaCha20-Poly1305 (および Encrypt-then-MAC を使用する CBC) に対して有効な攻撃が存在します。バイパスは chacha20-poly1305@openssh.com および (CBC が使用されている場合には) -etm@openssh.com MAC アルゴリズムで発生します。これはまた、3.1.0-SNAPSHOT より前の Maverick Synergy Java SSH API、2022.83 までの Dropbear、Erlang/OTP の 5.1.1 より前の Ssh、0.80 より前の PuTTY、2.14.2 より前の AsyncSSH、0.17.0 より前の golang.org/x/crypto、0.10.6より前の libssh、1.11.0 までの libssh2、3.4.6 より前の Thorn Tech SFTP Gateway、5.1 より前の Tera Term、3.4.0 より前の Paramiko、0.2.15 より前の jsch、2.5.6より前の SFTPGo、23.09.1 までの Netgate pfSense Plus、2.7.2 までの Netgate pfSense CE、18.2.0 までの HPN-SSH、1.3.8b より前 (および 1.3.9rc2 より前) の ProFTPD、2.3.4 より前の ORYX CycloneSSH、ビルド 0144 より前の NetSarang XShell 7、10.6.0 より前の CrushFTP、2.2.22 より前の ConnectBot SSH ライブラリ、2.11.0 までの Apache MINA sshd、0.37.0 までの sshj、20230101 までの TinySSH、trilead-ssh2 6401、LANCOM LCOS および LANconfig、3.66.4 より前の FileZilla、11.8 より前の Nova、14.4 より前の PKIX-SSH、9.4.3 より前の SecureCRT、5.10.4 より前の Transmit5、9.5.0.0p1-Beta より前の Win32-OpenSSH、6.2.2 より前の WinSCP、9.32 より前の Bitvise SSH Server、9.33 より前の Bitvise SSH Client、0.76.1.13 までの KiTTY、Ruby 用の net-ssh gem 7.2.0、Node.js 用の 1.15.0 より前の mscdex ssh2 モジュール、Rust 用の 0.35.1 より前の thrussh ライブラリ、Rust 用の 0.40.2 より前の Russh crate に影響を与えます。(CVE-2023-48795)

  - 1.3.8a より前の ProFTPD の main.c にある make_ftp_cmd に、1 バイトの領域外読み取りと、引用符/バックスラッシュのセマンティクスの不適切な処理によるデーモンクラッシュがあります。(CVE-2023-51713)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

According to the versions of the proftpd package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other     products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the     extension negotiation message), and a client and server may consequently end up with a connection for     which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because     the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and     mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of     ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and     (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API     before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80,     AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0,     Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15,     SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH     through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang     XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd     through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and     LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3,     Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server     before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the     mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh     crate before 0.40.2 for Rust. (CVE-2023-48795)

  - make_ftp_cmd in main.c in ProFTPD before 1.3.8a has a one-byte out-of-bounds read, and daemon crash,     because of mishandling of quote/backslash semantics. (CVE-2023-51713)
