Detailsinfo

A vulnerability classified as critical has been found in unitecms Unlimited Elements for Elementor Plugin up to 2.0.7 on WordPress. Affected is the function normalizeAjaxInputData. The manipulation of the argument filter_search with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Unlimited Elements for Elementor plugin for WordPress is vulnerable to SQL Injection via the 'data[filter_search]' parameter in the get_cat_addons AJAX action in versions up to and including 2.0.7. This is due to insufficient input sanitization and the use of deprecated escaping functions combined with direct string concatenation in SQL query construction. The vulnerability is exacerbated because the normalizeAjaxInputData() function calls stripslashes() on all user input, removing the protection provided by WordPress's wp_magic_quotes() function. Subsequently, the filter_search parameter is escaped using the deprecated wpdb->_escape() function and then directly concatenated into a LIKE clause without using prepared statements. This makes it possible for authenticated attackers, with Contributor-level access and above (who can obtain a valid nonce through the Elementor editor), to inject arbitrary SQL commands and extract sensitive information from the database.
