Vulnerability Overview

The Fusion Builder plugin for WordPress, an Avada theme core plugin, is vulnerable to Server-Side Request Forgery in versions up to 3.6.2 along with the Avada theme in versions up to 7.6.2. This is due to insufficient validation in one of its form parameters. This makes it possible for unauthenticated attackers to interact with internal network hosts via specially crafted requests and can lead to sensitive information disclosure on certain configurations such as AWS.

Technical Analysis

REMEDIATION: Update to version 3.6.2, or a newer patched version --- IDENTIFIER: CWE-918 (Server-Side Request Forgery (SSRF)) The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
