Description
Adobe ColdFusion 8.0.1 includes FCKEditor, a rich text editor component that is enabled by default and contains a file upload vulnerability. The vulnerable FCKEditor version allows unauthenticated users to upload arbitrary files through its file management functionality without proper validation or access controls. Attackers can exploit this weakness to upload malicious files, such as web shells or executable scripts, directly to the server.
