Problems with Crawler browser

Raul | Last updated: Aug 21, 2020 10:26PM UTC

Hi, good afternoon, I have been trying to test the latest crawler functionality and scan with the browser that has burp suite but I have had a problem when I crawl without the browser, it adds all the content to my sitemap but when I do it with the browser from burp suite only adds some links to me but I can visualize with the flow plugin that actually makes more requests to the page and finds many more links but does not add them. What is this problem due to? Why do I see more requests than links added to my sitemap?

Do you have any scope / filter rules set? Would it be possible to provide us with screenshots or screen records demonstrating your issue?

I'm not using any filter, I just start the program and then enter a site to do the crawl, with the flow plugin that allows you to see the requests that go out and come in, I can see that several requests are made to the site that I enter for it crawl but many links are not added. https://i.ibb.co/c6FS2tD/Sin-t-tulo.png Of the people 220 requests that were made 100 requests are to the page that you enter for the crawl but it does not add those links, only 3 links

Is the site publicly accessible? Would we be able to take a look?

I have the same problem. I can see scanner requests in flow extension, but endpoints not added to sitemap in target tab after end of crawling. No any scope / filter rules set. https://imgur.com/a/A0YBVRO

Is it possible to provide us with permission to test this site? If so, could you provide us with steps to reproduce the issue?

> Is it possible to provide us with permission to test this site? Yes, use max 5 threads please. > If so, could you provide us with steps to reproduce the issue? 1. Start Burp v2021.2.1 2. Install flow extension from BApp Store 3. Start New Scan -> Crawl -> Enter "https://travel.yandex.ru" from post below 4. You can see /api/... requests in Flow, but not /api section in Target tab

Thanks, Ilya. We will do some testing and get back to you.

Ilya, please review the feedback from our development team: All the API requests return JSON files, which are not added to the sitemap (we only add HTML and JS files).

> All the API requests return JSON files, which are not added to the sitemap (we only add HTML and JS files). Thanks for testing. But when I use proxy with browser and load "travel.yandex.ru", API requests with json response correctly adds to sitemap. It is intended behaviour? It looks a bit weird.
