CVE-2022-23043: File upload restriction bypass in Zenario CMS

February 24, 2022 (updated March 3, 2022)

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.
