How can i test multiple parameters?

[minchan02]

if i want test this url "http://test.com/?a=1&b=1",
'a' parameter is essential parameter that must not be omitted and i want test only about 'b' parameter
but this tool can't test about multiple parameter and just test about each parameter

If I'm understanding you correctly you hate it that it goes and tests all parameters one by one. So in your example it would first test a and then b. This happens in the bruteforcer.py on line 23. It gets all the parameters and then tests them all. This feature could be added by adding a -p flag with an extended name --parameter-xss or adding a <XSS> placeholder and checking if any of the parameters have a <XSS> as value and then only test those. Would be a nice feature especially if you have many parameters.

This would be a quick workaround for and the value of parameters should be <XSS:[default_value> like <XSS:test>. The problem is that if the default value has any special characters like <XSS:<test>>. Further testing and editing would be needed but yeah. I'm using this for the past month and it helps out really nice. Maybe there's a better way but it's useful and quite straight forward.

A quick and very dirty fix to use special characters on line 38. Checking for XSS:[default should maybe be a function and return the parameters and their default value. I don't know how time consuming that would be...
