CoreFTP Server FTP and SFTP Server version 2 build 674 suffer from a directory traversal vulnerability. By utilizing a directory traversal along with the FTP MDTM command, an attacker can browse outside the root directory to determine if a file exists based on return file size along with the date the file was last modified by using a ..\..\ technique.
