Vulnerability Overview

The hndtst_action_instance_callback AJAX call of the Handsome Testimonials & Reviews WordPress plugin before 2.1.1, available to any authenticated users, does not sanitise, validate or escape the hndtst_previewShortcodeInstanceId POST parameter before using it in a SQL statement, leading to an SQL Injection issue.

Technical Analysis

REMEDIATION: Update to version 2.1.1, or a newer patched version --- IDENTIFIER: CWE-89 (Improper 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.
