sshkey-grab

sshkey-grab このスクリプトは、ssh-agent のバグを利用して、エージェントに最後に追加された鍵を取得します。これにより、ssh-agent が終了されておらず、以前の鍵が削除された後に新しい鍵が追加されていない場合、ssh-add -t、-d、-D を介して ssh-agent から削除された鍵を復元できる可能性があります。このバグは報告されており、新しいバージョンの OpenSSH で修正される可能性があります。修正されると、このツールは動作しなくなります。 要件 grabagentmem.sh は、ターゲットマシン上で root アクセスと gdb が必要です...

CVE-2023-38408

OpenSSH 漏洞 - CVE-2023-38408 📚 简介 在 OpenSSH（9.3p2 版本之前）中发现了一个漏洞。OpenSSH 中 ssh-agent 的 PKCS11 功能存在搜索路径不够可信的问题，如果 agent 被转发到攻击者控制的系统（/usr/lib 中的代码加载到 ssh-agent 中并不一定安全），则可能导致远程代码执行。此漏洞允许攻击者控制服务器上转发的 agent 套接字，并能够在客户端主机文件系统上写入，从而以运行 ssh-agent 的用户权限执行任意代码。 在下面的示例中，我们可以简要观察从探索到入侵 alice 用户的步骤。 步骤 1 - 攻击...
