At a glance

CVE-2023-4252 is a medium-severity Improper Validation of Specified Quantity in Input vulnerability in the EventPrime WordPress plugin, affecting versions <= 3.3.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The EventPrime plugin for WordPress is vulnerable to booking payment bypass in all versions up to, and including, 3.3.2. This is due to the plugin relying on user supplied input to control pricing instead of server-side controls/validation. This makes it possible for unauthenticated attackers to make bookings paying less than the expected amount for a booking.

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 privileges on the target site, and no interaction from a victim user.

CWE-1284: Improper Validation of Specified Quantity in Input

The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.

Remediation

Update to version 3.3.3, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: EventPrime 3.3.3 closes this, and updating the plugin is the step that ends it.
