A vulnerability allowing unrestricted file uploads has been identified in GreenCMS versions through 2.3. The issue arises in the 'pluginAddLocal' function within 'index.php?m=admin&c=custom&a=pluginadd'. This vulnerability allows attackers to upload compressed files containing web shells, which are then decompressed into the website's root directory. Once the web shell is in place, it can be used to gain remote access to the server, potentially leading to data breaches, server manipulation, and other significant security risks.
No specific mitigation measures are known, but it is generally recommended to upgrade to a supported version of GreenCMS.
