Executive brief
The Iona theme for WordPress is vulnerable to a security flaw that allows unauthorized users to access sensitive files on the web server. By exploiting this vulnerability, an attacker could view configuration files containing database credentials, potentially leading to a full takeover of the website and its data. This issue affects all versions of the theme up to and including 1.0.8.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Iona theme for WordPress (versions <= 1.0.8) due to improper control of filenames in PHP include/require statements (CWE-98). An unauthenticated remote attacker can exploit this by sending crafted requests to include local files from the server's filesystem. Successful exploitation can lead to the disclosure of sensitive information, such as wp-config.php, or potentially remote code execution if combined with other techniques like log poisoning. As of the advisory date, no official patch has been released by the vendor.
