Override final ActiveScan values to insert custom payload?

Danny | Last updated: May 08, 2017 03:44PM UTC

Is there a way to override ActiveScan checks or the order of checks so a custom check is run last? I'm trying to detect a certain type of XSS attack in our application where we're using Selenium to detect if javascript actually executes or not. I'm trying to find a way to keep my custom attack in all the fields long enough to run the selenium checks. Either by putting it at the end, turning off all default checks and just run mine, or possible "pausing" the active scan long enough to run an external script. Any ideas/suggestions appreciated.

There isn't a way to reorder the checks that Burp performs. Actually, Burp deliberately sends its own test string for stored XSS last, to maximize the chances of it not getting overwritten. You could disable all of Burp's own active scan checks, so that yours is the only one that runs. That should do the job.
