File upload restriction bypass in Zenario CMS

  • Disclosed: 25.02.2022
  • Updated: 11.10.2026 10:22

Zenario CMS 9.2 allows an authenticated admin user to bypass the file upload restriction by creating a new 'File/MIME Types' using the '.phar' extension. Then an attacker can upload a malicious file, intercept the request and change the extension to '.phar' in order to run commands on the server.
