Description

The SEO Booster WordPress plugin before 3.8 allows for authenticated SQL injection via the "fn_my_ajaxified_dataloader_ajax" AJAX request as the $_REQUEST['order'][0]['dir'] parameter is not properly escaped leading to blind and error-based SQL injections.

• 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.
