Executive Summary

This vulnerability exists in GreenCMS up to version 2.3, specifically in the function pluginAddLocal within the file /index.php?m=admin&c=custom&a=pluginadd. It allows an attacker to perform an unrestricted upload, meaning they can upload files without proper restrictions or validation.

Impact Analysis

The unrestricted upload vulnerability can allow an attacker to upload malicious files to the affected system remotely. This could lead to unauthorized code execution, data compromise, or further exploitation of the system.
