Vulnerability details
The vulnerability allows a remote authenticated user to execute arbitrary code.
An issue was discovered in CutePHP CuteNews 2.1.2. An attacker can infiltrate the server through the avatar upload process in the profile area via the avatar_file field to index.php?mod=main&opt=personal. There is no effective control of $imgsize in /core/modules/dashboard.php. The header content of a file can be changed and the control can be bypassed for code execution.
