Vulnerability Overview

The SupportCandy – Helpdesk & Support Ticket System WordPress plugin before 2.2.7 does not have CSRF check in the wpsc_tickets AJAX action, nor has any sanitisation or escaping in some of the filter fields which could allow attackers to make a logged in user having access to the ticket lists dashboard set an arbitrary filter (stored in their cookies) with an XSS payload in it.

Technical Analysis

REMEDIATION: Update to version 2.2.7, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
