cscamp ctf 2012 - web 200

The web200 challenge requires an input which is a solution to an equation.

Also, submitting the answer after sometime results in a "too late" response. Inspecting the HTTP headers, there is a "Set-Cookie" and "EQ" header.

The value of the "EQ" HTTP header is base64 encoded which decodes to an array that contains the equation to be solved.

It requires automation due to the time bound nature of the challenge. Also, the cookie needs to be passed along with the POST request since it is used to track the answer of the corresponding "EQ" equation.
