Due to a security flaw in the file transfer programme CompleteFTP, unauthenticated attackers were able to delete arbitrary files on vulnerable installations.
CompleteFTP is a proprietary FTP and SFTP server for Windows developed by EnterpriseDT of Australia that supports FTPS, SFTP, and HTTPS. A security researcher known as rgod uncovered a problem in the HttpFile class that stems from the failure to properly validate a user-supplied path before utilising it in file operations.
