Technical details

The media.php module in CuteNews 2.1.2 fails to properly validate uploaded file types, allowing an authenticated user with Media Manager access to upload dangerous file types such as PHP scripts. An attacker with valid credentials can exploit this to achieve remote code execution in the context of the web application, establishing a reverse shell for complete server compromise.
