The version of SunSSH running on the remote host has an information disclosure vulnerability.  A design flaw in the SSH specification could allow a man-in-the-middle attacker to recover up to 32 bits of plaintext from an SSH-protected connection in the standard configuration.  An attacker could exploit this to gain access to sensitive information.

Note that this version of SunSSH is also prone to several additional issues but Nessus did not test for them.

According to its banner, the remote host appears to be running OpenSSH version older than 2.1.1. Such versions are reportedly affected by a local privilege esclation vulnerability.

If the UseLogin option is enabled, then sshd does not switch to the uid of the user logging in.  Instead, sshd relies on login(1) to do the job.  However, if the user specifies a command for remote execution, login(1) cannot be used and sshd fails to set the correct user id, so the command is run with the same privilege as sshd (usually root privileges).

リモートホストで実行されているバージョンの SunSSH に情報漏洩脆弱性があります。SSH の仕様の設計上の欠陥により、中間攻撃者が、標準構成の SSH 保護接続から最大 32 ビットまでの平文を回収できることがあります。攻撃者はこれを悪用して、機密情報にアクセスすることがあります。

このバージョンの SunSSH はいくつかのその他の問題の影響も受けやすくなっていますが、Nessus はそれらの問題をテストしていないことに、注意してください。

遠端主機上安裝的 SunSSH 版本有資訊洩漏弱點。SSH 規格的設計瑕疵允許攔截式攻擊者在標準組態中從 SSH 受保護的連線復原多達 32 位元的純文字。攻擊者可惡意利用此弱點來存取敏感資訊。

請注意，此版本的 SunSSH 也容易發生其他多個問題，但 Nessus 並未測試這些問題。

远程主机上运行的 SunSSH 版本存在信息泄露漏洞。SSH 规范中的设计缺陷可允许中间人攻击者从标准配置的受 SSH 保护的连接中恢复多达 32 位的明文。攻击者可利用这一点获取敏感信息的访问权限。

请注意，此 SunSSH 版本也易于发生多个其他问题，但 Nessus 未对其进行测试。

Note: NNM has solely relied on the banner of the SSH client to perform this check. Any backported patches or workarounds such as recompiling or edited configurations are not observable through the banner.
