一、Windows-Exploit-Suggester简介
1. 简介
Windows-Exploit-Suggester是受Linux_Exploit_Suggester的启发而开发的一款提权辅助工具,其官方下载地址:https://github.com/GDSSecurity/Windows-Exploit-Suggester,它是用python开发而成,运行环境是python3.3及以上版本,且必须安装xlrd 库(https://pypi.python.org/pypi/xlrd),其主要功能是通过比对systeminfo生成的文件,从而发现系统是否存在未修复漏洞。
2. 实现原理
Windows-Exploit-Suggester通过下载微软公开漏洞库到本地“生成日期+mssb.xls”文件,然后根据操作系统版本,跟systeminfo生成的文件进行比对。微软公开漏洞库下载地址:
http://www.microsoft.com/en-gb/download/confirmation.aspx?id=36982。同时此工具还会告知用户针对于此漏洞是否有公开的exp和可用的Metasploit模块。
二、使用Windows-Exploit-Suggester
1. 下载Windows-Exploit-Suggester、python3.3以及xlrd
- https://www.python.org/ftp/python/3.3.3/python-3.3.3.amd64.msi
- https://pypi.python.org/packages/42/85/25caf967c2d496067489e0bb32df069a8361e1fd96a7e9f35408e56b3aab/xlrd-1.0.0.tar.gz#md5=9a91b688cd4945477ac28187a54f9a3b
- https://codeload.github.com/GDSSecurity/Windows-Exploit-Suggester/zip/master
2. 本地安装
本地安装python3.3.3对应平台版本程序,安装完成后,将文件xlrd-1.0.0.tar.gz复制到python3.3.3安装目录下解压,然后命令提示符下执行setup.py install。否则***次执行会显示无结果,如图1所示,提示升级或者安装xlrd库文件。
图1提示安装xlrd库文件
3. 下载漏洞库
使用以下命令,将在本地文件夹下生成生成日期+mssb.xls”文件,比如使用命令会生成2017-03-20-mssb.xls文件,网上公开资料生成2017-03-20-mssb.xlsx是错误的,如图2所示,执行命令“windows-exploit-suggester.py --update”生成文件2017-03-20-mssb.xls。
图2生成漏洞库文件
4. 生成系统信息文件
使用“systeminfo > win7sp1-systeminfo.txt”命令生成win7sp1-systeminfo.txt文件,在真实环境中可以将生成的文件下载到本地进行比对。
5. 查看系统漏洞
使用命令“windows-exploit-suggester.py --database 2017-03-20-mssb.xls --systeminfo win7sp1-systeminfo.txt”查看系统存在的高危漏洞,如图3所示,对win7系统进行查看的结果,显示ms14-026为可以利用的PoC。

6. 查看帮助文件
windows-exploit-suggester.py -h查看使用帮助。
三、技巧与高级利用
1. 远程溢出漏洞
目标系统利用systeminfo生成文件,进行比对,例如对win2003生成的系统信息进行比对:
- windows-exploit-suggester.py --database 2017-03-20-mssb.xls --systeminfo win2003.txt
结果显示存在MS09-043、MS09-004、MS09-002、MS09-001、MS08-078和MS08-070远程溢出漏洞。
2. 所有漏洞审计
使用以下命令进行所有漏洞的审计,如图5所示,对windows2003 服务器进行审计发现存在24个漏洞。“--audit -l”对本地溢出漏洞进行审计,“--audit -r”对远程溢出漏洞进行审计。
- windows-exploit-suggester.py --audit --database 2017-03-20-mssb.xls --systeminfo win2003.txt
图5审计所有漏洞
3. 搜索本地可利用漏洞信息
“-l”参数比较 78 补丁,137已知漏洞。带“-l”参数搜索本地存在的漏洞命令如下:
- windows-exploit-suggester.py --audit -l --database 2017-03-20-mssb.xls --systeminfo win2003-2.txt
通过审计本地漏洞发现Windows 2003 server未安装SP2补丁,存在多个本地溢出漏洞,在选择上,选择***的漏洞号进行利用,成功性会高很多,例如在本次实验机上新建一个普通账号temp,登录以后将MS15-077漏洞利用程序进行利用,效果如图6所示。
