CVE-2016-20103

Cherry Plugin for WordPress before 1.2.7 contains a path traversal vulnerability that allows unauthenticated attackers to download arbitrary files via the 'file' parameter. Attackers can send GET requests to /admin/import-export/download-content.php with traversal sequences like ../../../../../wp-config.php to read database credentials, since the script passes input directly to readfile(). Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
