At a glance

CVE-2024-7573 is a medium-severity Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in the Relevanssi Live Ajax Search WordPress plugin, affecting versions <= 2.4. 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 2.5; sites on affected versions should update now. Disclosed August 2024, reported by scottaglia.

Vulnerability Overview

The Relevanssi Live Ajax Search plugin for WordPress is vulnerable to argument injection in all versions up to, and including, 2.4. This is due to insufficient validation of input supplied via POST data in the 'search' function. This makes it possible for unauthenticated attackers to inject arbitrary arguments into a WP_Query query and potentially expose sensitive information such as attachments or private posts.

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-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.

Remediation

Update to version 2.5, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Relevanssi Live Ajax Search 2.5 closes this, and updating the plugin is the step that ends it.
