「白帽黑客成长记」Windows提权基本原理（上）
https://www.cnblogs.com/ichunqiu/p/10949592.html
我们通常认为配置得当的Windows是安全的，事实真的是这样吗？今天让我们跟随本文作者一起深入了解Windows操作系统的黑暗角落，看看是否能得到SYSTEM权限。
作者将使用不同版本的Windows来强调任何可能存在的命令行差异，请牢记因为不同的操作系统和版本差异会在命令行中显现，作者试图构造本教程，以便它适用于Windows提权的最普遍的方式。
注：文章篇幅较长，阅读用时约10分钟。
必要文档补充：
Encyclopaedia Of Windows Privilege Escalation (Brett Moore)
Windows Attacks: AT is the new black (Chris Gates & Rob Fuller)
Elevating privileges by exploiting weak folder permissions (Parvez Anwar)
译者注：原文作者提到了meterpreter，我们可以把meterpreter比做sql注入利用的sqlmap，在得到meterpreter的shell后，可以输入命令getsystem，自动完成提权。
在t0-t3阶段，最初的信息收集方法
最开始是一个低权限的shell，这个shell可能是通过远程代码执行、钓鱼、反弹得到的。
在最开始的阶段，我们要快速收集一些基本信息来评估我们的环境。
第一步，找到连接的操作系统。
C:\Windows\system32> systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
OS Name: Microsoft Windows 7 Professional
OS Version: 6.1.7601 Service Pack 1 Build 7601
接下来，我们将看到主机名和连接上的对应用户。
C:\Windows\system32> hostname
b33f
C:\Windows\system32> echo %username%
user1
现在我们得到了一些基本信息，然后列出其他用户的帐户，并在更详细的情况下查看用户信息。
这里会看到user1不是本地组管理员。
C:\Windows\system32> net users
User accounts for \\B33F
-------------------------------------------------------------------------------
Administrator b33f Guest
user1
The command completed successfully.
C:\Windows\system32> net user user1

以上是我们目前需要了解的关于用户和权限的全部内容。接下来我们要讨论的是网络信息，连接的设备，以及相应规则。
首先看一下可用的网络接口和路由表。

在t4阶段，神秘艺术之WMIC
WMIC（Windows Management Instrumentation Command-Line，Windows管理工具命令行），是Windows最有用的命令行工具之一。
WMIC对于信息收集和渗透是非常实用的，而且输出内容有很多值得期待的地方。全面解释WMIC的使用将需要一个教程，由于格式化的问题，WMIC有些输出将很难显示。
下面列出两个文章，对于WMIC是非常值得阅读的：
- Command-Line Ninjitsu (SynJunkie)
- Windows WMIC Command Line (ComputerHope)
一些默认配置的Windows并不允许访问WMIC，除非是用户在Windows的管理组，从虚拟机测试来看，任何版本的Windows XP的低权限用户并不能访问WMIC。相反的，默认配置的Windows 7专业版和Windows 8企业版允许低权限的用户访问WMIC并查询操作系统版本。
这正是我们所需要的，因为我们正在使用WMIC来收集关于目标机的信息。关于WMIC的选项，列出了下面可用的命令行：
C:\Windows\system32> wmic /?
[global switches]
The following global switches are available:
/NAMESPACE Path for the namespace the alias operate against.
/ROLE Path for the role containing the alias definitions.
/NODE Servers the alias will operate against.
/IMPLEVEL Client impersonation level.
/AUTHLEVEL Client authentication level.
/LOCALE Language id the client should use.
/PRIVILEGES Enable or disable all privileges.
/TRACE Outputs debugging information to stderr.
/RECORD Logs all input commands and output.
/INTERACTIVE Sets or resets the interactive mode.
/FAILFAST Sets or resets the FailFast mode.
/USER User to be used during the session.
/PASSWORD Password to be used for session login.
/OUTPUT Specifies the mode for output redirection.
/APPEND Specifies the mode for output redirection.
/AGGREGATE Sets or resets aggregate mode.
/AUTHORITY Specifies the for the connection.
/?[:<BRIEF|FULL>] Usage information.
For more information on a specific global switch, type: switch-name /?

为了简化操作，我已经创建了一个脚本，可以在目标机器上使用WMIC提取以下信息：流程、服务、用户帐号、用户组、网络接口、硬盘信息、网络共享信息、安装Windows补丁、程序在启动运行、安装的软件列表、操作系统、时区信息。
通过各种标志和参数来提取有价值的信息，如果有人想要添加到列表中，请在下面留下评论。使用内置的输出特性，脚本将把所有结果写入可读的html文件。
