At a glance

CVE-2023-5054 is a medium-severity Missing Authorization vulnerability in the Super Store Finder WordPress plugin, affecting versions <= 6.9.3. It carries a CVSS score of 5.8 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 6.9.4; sites on affected versions should update now. Disclosed September 2023, reported by Etharus.

Vulnerability Overview

The Super Store Finder plugin for WordPress is vulnerable to unauthenticated arbitrary email creation and relay in versions up to, and including, 6.9.3. This is due to insufficient restrictions on the sendMail.php file that allows direct access. This makes it possible for unauthenticated attackers to send emails utilizing the vulnerable site's server, with arbitrary content. Please note that this vulnerability has already been publicly disclosed with an exploit which is why we are publishing the details without a patch available, we are attempting to initiate contact with the developer.

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-862: Missing Authorization

Reaching this weakness in Super Store Finder <= 6.9.3 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Super Store Finder the fix is 6.9.4: builds <= 6.9.3 are affected, anything from 6.9.4 onward is not.

Remediation

Update to version 6.9.4, 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: Super Store Finder 6.9.4 closes this, and updating the plugin is the step that ends it.
