Vulnerability Overview

The Event Manager and Tickets Selling for WooCommerce WordPress plugin before 3.5.8 does not validate and escape the post_author_gutenberg parameter before using it in a SQL statement when creating/editing events, which could allow users with a role as low as contributor to perform SQL Injection attacks

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Event Booking Manager for WooCommerce < 3.5.8 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Event Booking Manager for WooCommerce the fix is 3.5.8: builds < 3.5.8 are affected, anything from 3.5.8 onward is not.

Remediation

Update to version 3.5.8, or a newer patched version

How does WordSec protect against this?
