The Accellion Secure File Transfer SFTP Satellite ships with SSH tunneling enabled. An authorized SFTP user can connect to the SFTP satellite and leverage the SSH tunneling functionality to attack localhost bound ports that are not intended to be exposed externally. By leveraging trust assumptions in the running Rsync daemon, sensitive files including the MySQL root password are retrievable. This password can be used when connecting to the MySQL database, also running on localhost, and the password hashes of all users configured on the server can be retrieved. Accellion released a software update to version FTA_9_8_70 on the 4th of December 2013 which disables SSH tunneling and prevents this issue being exploited.
