WatchGuard Firebox SOHO contains a flaw that may allow a remote attacker to gain access to the FTP service. The issue is due to the FTP service not requiring a valid user name to log in. This allows an attacker to more easily brute force a valid password without the need of a matching account. If compromised, the firewall configuration and other sensitive information could be downloaded.
