Sources and claim methodology

Upstream source description

UnoPim before 2.1.5 contains an authenticated file upload vulnerability that allows authenticated administrators to upload arbitrary PHP files through the TinyMCE image upload endpoint due to missing file extension and MIME type validation. Attackers can upload a PHP web shell to the public storage disk and execute arbitrary operating system commands on the server by accessing the uploaded file at the URL returned in the server response.
