Vulnerability Overview

The Beaver Builder Plugin (Starter Version) plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'save_enabled_icons' function in all versions up to, and including, 2.9.1. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The vulnerability was partially patched in version 2.9.1.

Technical Analysis

REMEDIATION: Update to version 2.9.1.1, or a newer patched version --- IDENTIFIER: CWE-434 (Unrestricted Upload of File with Dangerous Type) The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
