Executive brief
The Nexio theme for WordPress is vulnerable to a security flaw that allows unauthorized users to access sensitive files on the server. By exploiting this, an attacker could view configuration files containing database credentials, potentially leading to a full takeover of the website and its data. This vulnerability is particularly serious as it does not require a login to exploit.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Nexio 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 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, which may facilitate further attacks including database compromise or remote code execution. As of the advisory date, no official patch is available, though third-party mitigation rules have been released.
