File upload restriction bypass in Zenario CMS
The advisory, in context
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.
