At a glance

CVE-2024-6010 is a medium-severity External Control of Assumed-Immutable Web Parameter vulnerability in the Cost Calculator Builder PRO WordPress plugin, affecting versions <= 3.2.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.2.2; sites on affected versions should update now. Disclosed September 2024, reported by andrea bocchetti.

Vulnerability Overview

The Cost Calculator Builder PRO plugin for WordPress is vulnerable to price manipulation in all versions up to, and including, 3.2.1. This is due to the plugin allowing the price field to be manipulated prior to processing via the 'create_cc_order' function, called from the Cost Calculator Builder plugin. This makes it possible for unauthenticated attackers to manipulate the price of orders submitted via the calculator. Note: this vulnerability was partially patched with the release of Cost Calculator Builder version 3.2.17.

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-472: External Control of Assumed-Immutable Web Parameter

Cost Calculator Builder PRO <= 3.2.1 carries this weakness at create_cc_order, and reaching it takes no account at all. External control of an assumed-immutable parameter means the code trusts a value it believes cannot be changed by the caller, when in fact the request carries it.

Editing that field changes the outcome of the operation, which on commerce plugins means altered prices or totals and on account flows means acting as another user. For Cost Calculator Builder PRO the fix is 3.2.2: builds <= 3.2.1 are affected, anything from 3.2.2 onward is not.

Remediation

Update to version 3.2.2, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Cost Calculator Builder PRO 3.2.2 closes this, and updating the plugin is the step that ends it.
