Description
The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the eh_crm_new_ticket_post() function in all versions up to, and including, 3.3.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
