Incomplete blacklist vulnerability in config.template.php in vtiger CRM before 5.2.1 allows remote authenticated users to execute arbitrary code by using the draft save feature in the Compose Mail component to upload a file with a .phtml extension, and then accessing this file via a direct request to the file in the storage/ directory tree.
