Vulnerability Overview

The Oxygen Builder plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.8.2 via post metadata. This is due to the plugin storing custom data in post metadata without an underscore prefix. This makes it possible for lower privileged users, such as contributors, to inject arbitrary PHP code via the WordPress user interface and gain elevated privileges.

Technical Analysis

REMEDIATION: Update to version 4.8.3, or a newer patched version --- IDENTIFIER: CWE-94 (Improper Control of Generation of Code ('Code Injection')) The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
