Description
The CMP – Coming Soon & Maintenance WordPress plugin before 4.1.20 does not correctly restrict access to the site while maintenance/coming-soon mode is enabled, allowing unauthenticated visitors to bypass the coming-soon page and reach the otherwise hidden site, including hidden published pages, by shaping the request so it is mistaken for a login request.

Executive Summary

The CMP – Coming Soon & Maintenance WordPress plugin before version 4.1.20 has a flaw where unauthenticated visitors can bypass the maintenance or coming-soon mode by crafting requests that appear as login attempts. This allows them to access hidden parts of the site, including published pages that should remain restricted during maintenance.

Detection Guidance

Check if the CMP – Coming Soon & Maintenance WordPress plugin version is below 4.1.20. You can do this by logging into your WordPress admin panel, navigating to Plugins, and looking for the plugin version. Alternatively, use WP-CLI with the command: wp plugin list --name='cmp-coming-soon-and-maintenance' to check the installed version.

Impact Analysis

This vulnerability allows unauthorized users to view private or restricted content on your WordPress site while it is in maintenance or coming-soon mode. This could expose sensitive information, drafts, or pages meant to be hidden from public access.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by exposing restricted or sensitive site content during maintenance mode. Unauthorized access to hidden pages may lead to unintended disclosure of personal or protected health information, violating data protection requirements.

Mitigation Strategies

Update the CMP – Coming Soon & Maintenance plugin to version 4.1.20 or later immediately. If updating is not possible, consider temporarily disabling the plugin until an update can be applied. Ensure your WordPress site is not in maintenance or coming-soon mode during this process.
