WordPress Plugin Vulnerabilities

Events Made Easy < 2.2.24 - Admin+ Stored Cross-Site Scripting

Description

The plugin does not sanitise and escape Custom Field Names, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

Proof of Concept

Add/Edit a Custom Field (/wp-admin/admin.php?page=eme-formfields) and put the following payload in the Field Name: a<script>alert(/XSS/)</script>

The XSS will be triggered when accessing some pages like Custom Field, Pending Bookings, Approved Bookings

Affects Plugins

Fixed in 2.2.24
