Cockpit: cockpit: unauthenticated remote code execution due to ssh command-line argument injection

Cockpit's remote login feature passes user-supplied hostnames and usernames from the web interface to the SSH client without validation or sanitization. An attacker with network access to the Cockpit web service can craft a single HTTP request to the login endpoint that injects malicious SSH options or shell commands, achieving code execution on the Cockpit host without valid credentials. The injection occurs during the authentication flow before any credential verification takes place, meaning no login is required to exploit the vulnerability.

Cockpit 操作系统命令注入漏洞

Cockpit是Cockpit开源的一个交互式服务器管理界面。 Cockpit存在操作系统命令注入漏洞，该漏洞源于远程登录功能将用户提供的主机名和用户名传递给SSH客户端时未经验证或清理，可能导致具有网络访问权限的攻击者通过单个HTTP请求注入恶意SSH选项或shell命令，从而在无需有效凭据的情况下在主机上执行代码。
