Automatically change Response to a specific body

Farid110 | Last updated: Dec 08, 2021 04:35PM UTC

Hi I want to change Response body of some requests automatically but I don't know how to do it. For example I have a request sent to example.com/api/hello where the response of request leads me to example.com/api/howAreYou so I need to basically implement something that can distinguish between URLs and change my Respnse body to something specific. I managed to do it by intercepting Response Request MANUALLY (I had already added URLs to my Target scope) and since I'm using a python script for sending my requests, It is now wise to modify each Response manually. So I want implement something that can intercept and modify Response body AUTOMATICALLY. https://forum.portswigger.net/thread/automatically-change-response-a5c9cd47 I saw this thread which was similar to my question but I quite don't know how and where to get started. I can develop python script but I can't get docs and usage instruction of developing Extensions for it. I'll be really grateful if you could guide me in this specific scenario.

Hi Thanks for your reply. I managed to grasp some info about Burp API. But I'm somehow stuck in conditioning based on specific URL. This script modifies body where Target HOST condition is met. But I can't use it because in my I use internal links of the same website. For example when script gets the Host of http://example.com/hello it returns "example.com" and it again returns the same answer for http://example.com/howAreYou which prevents me to modify response accordingly. I want separate modifications for each of those internal links and this script/plugin is unable to provide that feature. I even managed to modify the script and call getHeaders() method for REQUESTS, which somehow provides me the internal links but I can't get the URL of RESPONSE by any of these methods. I need something like getURL() for RESPONSE and burp API doesn't seem to be providing that. I'd be thankful if your could help me and lead me in a direction to solve it or even introduce a new script which is similar with what I'm trying to do. Thanks
