How can I scan via Burp Pro API /scan with authentication script

thanhpt | Last updated: Aug 18, 2023 10:23AM UTC

I am using BurpSuite Professional in run in headless mode on my server. I also load user config to BurpSuite and open API runs on http://localhost:1337. When I create a scan via API /scan, in field "applications_login", I passed my recorded login from Burp Navigation Recorder. But after I call API /scan/task_id, the scan status is "paused" and crawl_and_auditing_caption is "Paused task due to: Crawl was configured to use Burp's browser but a browser could not be started". How can I run scan authenticated in headless mode via API?

Hi

When you start Burp, are you using the --unpause-spider-and-scanner command-line argument?

Yes, I ran BurpSuite with unpause-spider-and-scanner option. I also create a scan without authentication and it ran successfully without error. But when I start scan with authentication and script from Burp Recorder, it continue show that Burp browser couldn't be started. Is there any chances that Burp Browser can not run in headless mode?

I forgot to mention that I run BurpSuite Pro on Ubuntu server with no GUI. When I run on Windows server, there is no error like that.

Hi It sounds like the browser that Burp uses for scanning is not able to be launched. Could you check the permissions on your browser binaries and try to launch Chromium headlessly? When launching Chromium, do you receive any error messages? If you're having issues locating your browser binaries, using the "--diagnostics" flag, will print out the browser binary location.

The "--diagnostics" flag didn't show any errors. But I tried to install the chromium on Ubuntu server so it works, turn out in commandline mode, Burp Browser still requires some library that need browser to start. These libraries come with Chromium installation but are not included in Docker. Install Chromium first solved my problem. Thankyou.
