Vulnerability Overview

An unauthenticated SQL Injection vulnerability in Good Layers LMS Plugin <= 2.1.4 exists due to the usage of "wp_ajax_nopriv" call in WordPress, which allows any unauthenticated user to get access to the function "gdlr_lms_cancel_booking" where POST Parameter "id" was sent straight into SQL query without sanitization.

Technical Analysis

REMEDIATION: Update to version 2.1.5, 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.
