Vulnerability Overview

The The Eventer - WordPress Event & Booking Manager Plugin plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 3.11.2.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The vulnerability was partially patched in version 3.10.0, 3.11.2, and 3.11.2.1.

Technical Analysis

REMEDIATION: Update to version 3.11.2.2, 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.
