In HylaFAX Enterprise Web Interface and AvantFAX, the language form element is not properly sanitized
before being used and can be misused to include an arbitrary file in the
PHP code allowing an attacker to do anything as the web server user.
This flaw requires the attacker to be authenticated with a valid user account.
