Executive brief
The Resurs 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 information, potentially leading to a full site takeover. This issue affects all versions of the theme up to 1.3, and there is currently no official patch available from the developer.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Resurs theme for WordPress (versions <= 1.3) due to improper control of filenames in PHP 'include' or 'require' statements (CWE-98). An unauthenticated remote attacker can exploit this by sending specially crafted requests to the server to include and execute local files. 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 find a way to execute malicious code via included files. As of the advisory date, no official patch has been released, and users are advised to use web application firewalls or third-party security rules to mitigate the risk.
