[ Introduction ]

(*) 2wire Gateway User Interface: It Work with the Modems / Routers

of 2Wire, Inc., it take the work out of manage a local network.

the Users see important information about the DSL connection,

devices on the network, firewall logs, and more. Optional notification

features let users know if there is a problem and guides them to a fix.

(*) CRLF: It's a special character or sequence of characters

signifying the end of a line of text.

[Char] [ Complete name ] [Hex] [ascii]

CR = Carriage Return = A = 10

LF = Line_Feed = D = 13

[ Explanation ]

When a evil request is maked and sended at 2wire Webserver

and this can't process the request, result as a Denegation

of service (DoS).

The error comes at the moment of include a End_of_line (CRLF)

into any variable, when we're using a GET method it's

imposible (inside a normal situation), but, it's really true?..
