  script_tag(name:"insight", value:"The flaws are due to:

  - The TestTelnetConnection.jsp does not validate the user input, allowing
  an attacker to execute arbitrary commands in the server side with the
  privileges of asadmin user.

  - TestDRConnection.jsp, shows the file path in the error messages, this is
  considered a minor information leak.

  - Without being authenticated, any user is able to manipulate the message
  of the default error page, helping him to develop social engineering
  attacks.

  - ServerAdmin/ErrorViewer.jsp in DS3 Authentication Server allow remote attackers to inject arbitrary error-page text via the message parameter.");
