Executive brief
The Google Review Slider plugin for WordPress, which allows businesses to display Google reviews on their websites, contains a security flaw. An attacker can use this vulnerability to access and extract sensitive information from the website's database without needing a password. This could lead to the exposure of customer data, site configuration details, or other private information stored on the server.
Technical details
A time-based blind SQL injection vulnerability exists in the Google Review Slider plugin for WordPress (version 6.1 and earlier). The flaw is located in the 'tid' parameter within the admin interface, specifically affecting GET requests to 'admin.php?page=wp_google-templates_posts'. Because the plugin fails to properly sanitize the 'tid' input before using it in a database query, an unauthenticated remote attacker can inject malicious SQL commands. By measuring the time delay in the server's response, an attacker can systematically extract sensitive data from the WordPress database. The issue was addressed in version 6.2.
