Audit problems at 95%

Gabriel | Last updated: Jun 02, 2020 06:16AM UTC

Hi, I have the following configuration: - Ubuntu 20.20 - Burp Suite Pro v2020.4.1 - openjdk 13.0.3 I am running Burp using the jar file and I am starting a scanning using the API. Once the audit scanning gets to 95%, the requests per second made by Burp go down to 0 (typically there are 40 requests/s) for about 15 - 20 minutes. After this period, the scanning percentage gets to about 56% and it will continue the scan until it gets to 100% and finishes. What is the reason for having the scanning stuck at 95% and then lowering the percentage back to 55%?

Thanks for this report. Do you have performance feedback enabled (User options > Misc > Performance feedback)? If so, could you provide us with your diagnostics (Help > Diagnostics)?

Hi, No, I don't have the performance feedback enabled. Is there a way to see what attack is Burp trying when the problem occurs?

You can try using the Logger++ and Flow extensions from the BApp store: - https://portswigger.net/bappstore/470b7057b86f41c396a97903377f3d81 - https://portswigger.net/bappstore/ee1c45f4cc084304b2af4b7e92c0a49d Let us know if you find something interesting.

Hi, Unfortunately, I was not able to find the reason of this bahavior yet. I have sent you an email with Diagnostics.

Thanks, Gabriel. We'll investigate and get back to you.
