Executive brief
The Billey theme for WordPress is vulnerable to a security flaw that allows authenticated users to access sensitive files on the web server. By exploiting this issue, an attacker could view internal configuration files, such as those containing database credentials, potentially leading to a full site takeover. This affects websites using the Billey theme version 2.1.8 and earlier.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeMove Billey theme for WordPress (versions <= 2.1.8) due to insufficient validation of user-supplied input used in PHP include or require statements (CWE-98). An attacker with at least 'Contributor' level privileges can manipulate file paths to include and execute local files on the server. This can lead to the exposure of sensitive information, such as wp-config.php, 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.
