Vulnerability Overview

The OpenHook plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 4.3.0 via the 'php' shortcode. This allows authenticated attackers with subscriber-level permissions or above, to execute code on the server. This requires the [php] shortcode setting to be enabled on the vulnerable site.

Technical Analysis

REMEDIATION: Update to version 4.3.1, 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.
