CVE-2024-3957 is a medium-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Booster for WooCommerce WordPress plugin, affecting versions <= 7.1.8.

Vulnerability Overview

The Booster for WooCommerce plugin is vulnerable to Unauthenticated Arbitrary Shortcode Execution in versions up to, and including, 7.1.8. This allows unauthenticated attackers to execute arbitrary shortcodes. The severity and exploitability depends on what other plugins are installed and what shortcode functionality they provide.

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-94: Improper Control of Generation of Code ('Code Injection')

Reaching this weakness in Booster for WooCommerce <= 7.1.8 takes no account at all. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For Booster for WooCommerce the fix is 7.1.9: builds <= 7.1.8 are affected, anything from 7.1.9 onward is not.

Remediation

Update to version 7.1.9, 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. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Booster for WooCommerce 7.1.9 closes this, and updating the plugin is the step that ends it.
