WordPress Plugin Vulnerabilities

EventON < 2.2 - Admin + Stored HTML Injection

Description

The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored HTML Injection attacks even when the unfiltered_html capability is disallowed.

Proof of Concept

1. Go to the Virtual Event -> This is a virtual (online) event.

2. Configure Virtual Event Details -> On the second field, the URL field and insert '"><a href="https://miguelsantareno.github.io/resources.html">Clickme!</a> or '"><img src=X>click, and the HTML Injection Stored would appear.

Affects Plugins

Fixed in 2.2
