Vulnerability Overview

The EventON plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'eid' parameter in all versions up to, and including, 4.5.4 (premium) & 2.2.7 (free) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 2.2.8, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
