At a glance

CVE-2023-2897 is a low-severity Use of Less Trusted Source vulnerability in the Brizy WordPress plugin, affecting versions <= 2.4.18. It carries a CVSS score of 3.7 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 2.4.19; sites on affected versions should update now. Disclosed May 2023, reported by Alex Thomas.

Vulnerability Overview

The Brizy Page Builder plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 2.4.18. This is due to an implicit trust of user-supplied IP addresses in an 'X-Forwarded-For' HTTP header for the purpose of validating allowed IP addresses against a Maintenance Mode whitelist. Supplying a whitelisted IP address within the 'X-Forwarded-For' header allows maintenance mode to be bypassed and may result in the disclosure of potentially sensitive information or allow access to restricted functionality.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-348: Use of Less Trusted Source

The product has two different sources of the same data or information, but it uses the source that has less support for verification, is less trusted, or is less resistant to attack.

Remediation

Update to version 2.4.19, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Brizy: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Brizy 2.4.19 closes this, and updating the plugin is the step that ends it.
