A vulnerability allowing unrestricted file uploads has been identified in GreenCMS versions through 2.3. The issue arises in the theme addition feature, accessed via 'index.php?m=admin&c=custom&a=themeadd', where uploaded files are not properly validated or filtered. This flaw enables attackers to upload compressed files containing web shells, which are then automatically decompressed into the website's root directory. Once the web shells are in place, tools like Godzilla can be used to gain control of the server, leading to serious security risks such as data breaches and malicious activities.
