Turbo Intruder - race-single-packet-attack.py Not queueing requests

J | Last updated: Oct 27, 2023 08:31PM UTC

Hello, I'm doing some research regarding James Kettle's single packet race conditions. I've tried his probe script as well as race-single-packet-attack.py but it doesn't actually queue the requests. The majority of the requests are received +1 second apart.

Also, Tried this on http2 server using Engine.BURP2 but I'm getting: AttributeError: class Engine has no attribute 'BURP2'

Hi Can you provide more detail on the issue you are seeing, please? - Which version of Burp are you using? - Are you using one of the same scripts, or have you used those as a template and modified it? - Are any errors reported? - If you test this out on one of the race condition labs in our Web Security Academy, for example https://portswigger.net/web-security/race-conditions/lab-race-conditions-bypassing-rate-limits, what do you see?
