Something to be aware of when calling defs is that their output is rendered straight to the context output buffer it isn t actually returned. If you look at the cached template example again, it should be clear why. Each line of source template is wrapped in an __M_writer() call, which has the effect of calling context.write(). If you want to actually capture the output of a def to a variable rather than to the output buffer, you have to use capture(). For example, consider this: <%def name="add(num1, num2)"> ${num1+num2} </%def> <%def name="display(num1, num2, result)"> The result of ${num1} + ${num2} is ${result} </%def> ${display(1, 2, add(1,2))} Running this example produces the following HTML source (although you won t see the line breaks in a web browser): 3 The result of 1 + 2 is None What happens here is that the output of the add() def is written to the output buffer, not captured and passed to the display() def. The add() def actually returns None, which is the value returned by ordinary Python functions if no value is explicitly returned. Instead, you want to capture the output from the add() def. You can do this by modifying the line that calls it to look like this: ${display(1, 2, capture(add, 1, 2))}

Since he does not have access to the secret key used in the MAC computation, the only feasible way for the attacker to obtain a correct action token would be to use our application as an oracle. However, to do so he would need the inputs to the MAC computation in particular, the user s session cookie. We can assume that the attacker does not have the ability to obtain cookies in our application s domain from within the user s browser otherwise he could already hijack the user s session directly. At the same time, our application generates session cookies such that it is infeasible for an attacker to guess other users session cookies (if this were possible, the attacker could hijack other users sessions simply by successfully guessing their session cookies). This means that the attacker s malicious page is effectively unable to populate and submit a request with an action token value that matches what our application expects, and such requests will not be processed.

The capture function is one of Mako s built-in template variables. It takes the def to capture as the first argument and the values to pass to the def as the subsequent arguments.
