Executive brief
The Deliciosa theme for WordPress is vulnerable to a security flaw that allows unauthorized individuals to access sensitive files on the web server. By exploiting this vulnerability, an attacker could view configuration files containing database credentials or other private system data, potentially leading to a full site takeover. This issue affects websites using the Deliciosa theme version 1.10.0 or earlier.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Deliciosa theme for WordPress (versions <= 1.10.0) due to improper control of filenames in PHP include/require statements (CWE-98). An unauthenticated remote attacker can exploit this by sending specially crafted requests to include local files from the server's filesystem. Successful exploitation can lead to the disclosure of sensitive information, such as the wp-config.php file containing database credentials, or potentially remote code execution if the attacker can upload or influence the content of a local file. As of the advisory date, no official patch has been released by the developer.
