CVE-2022-44136Public exploitNetwork attack vector

Unauthenticated code execution via User Form uploads

Published Nov 30, 2022 · Updated Apr 24, 2025

Remote code execution in Zenario CMS 9.3.57186 allows remote attackers to execute arbitrary PHP code through a User Form upload. The User Form module's upload path accepts attacker-supplied executable files without adequately rejecting dangerous file types. No authentication is required, but the site must expose a contact or other user form with file uploads enabled; exploitation runs the uploaded PHP payload.
