The remote host is vulnerable to multiple attack vectors.
The remote server is running the Ruby on Rails web application. This version of Rails is reported to be vulnerable to a number of flaws. It is reported that a remote attacker can perform man-in-the-middle attacks and gain user credentials. It is also reported that there is a content-parsing flaw in the XML handler that would allow an attacker to either gain unauthorized access to data or cause the application to fail.
Upgrade to version 1.2.5 or higher.
