Description

The JetEngine plugin for WordPress is vulnerable to SQL injection in all versions up to and including 3.8.10.1. The listing_load_more AJAX handler accepts a filtered_query parameter that is intentionally excluded from the HMAC query signature check to support front-end filter integration. However, meta_query row values within filtered_query are not sanitized before being merged into SQL construction. This makes it possible for unauthenticated attackers to perform time-based or boolean blind SQL injection by appending a malicious meta_query value to a Load More AJAX request captured from any public Listing Grid page.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
