Detailsinfo

A vulnerability classified as critical was found in WP Review Slider Pro Plugin up to 12.6.8 on WordPress. This vulnerability affects the function get_results of the component AJAX Action Handler. The manipulation of the argument curselrevs with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The WP Review Slider Pro plugin for WordPress is vulnerable to SQL Injection via the 'curselrevs[]' parameter of the wpfb_find_reviews AJAX action in versions up to, and including, 12.6.8. This is due to the handler reading $_POST['curselrevs'] raw with no sanitization or type casting, then concatenating each array element directly into a `WHERE id IN ( ... )` clause without quoting and executing via $wpdb->get_results() without $wpdb->prepare(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
