CuteFlow version 2.11.2 and earlier contains an arbitrary file upload vulnerability in the restart_circulation_values_write.php script. The application fails to validate or restrict uploaded file types, allowing unauthenticated attackers to upload arbitrary PHP files to the upload/___1/ directory. These files are then accessible via the web server, enabling remote code execution.
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
