Vulnerability Overview

The EventON plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including 3.0.5. This is due to insufficient escaping and sanitization on the q= parameter. 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. Please note this only affects the premium version of this plugin.

Technical Analysis

REMEDIATION: Update to version 3.0.6, 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.
