At a glance

CVE-2024-7410 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the My Custom CSS PHP & ADS WordPress plugin, affecting versions <= 3.3. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed August 2024, reported by stealthcopter.

Vulnerability Overview

The My Custom CSS PHP & ADS plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 3.3. This is due the plugin not preventing direct access to the /my-custom-css/vendor/mobiledetect/mobiledetectlib/export/exportToJSON.php file and and the file displaying/generating the full path. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in My Custom CSS PHP & ADS <= 3.3 takes no account at all. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. No fixed build of this plugin is recorded for My Custom CSS PHP & ADS yet, so installs running <= 3.3 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
