Description · from the CVE record

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.3.7 via the initMailPart function. This is due to insufficient file type validation when saving IMAP email attachments. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
