Smuggle Probe Fails To Detect the Vulnerability on Basic Web Academy Lab #52

Closed FahadSec closed 2 years ago

FahadSec commented 2 years ago

I have Burp Suite Professional Version 2022.5.2 on Mac OS.

I attempted to test the HTTP Request Smuggler Probe on the PortSwigger Web Academy Request Smuggler Lab 1: HTTP request smuggling, basic CL.TE vulnerability but the extension failed to detect it. I tried unloading all my extensions and it still didn't work.

Attached the request logs.

Thanks for the report, this was really useful. I've investigated and found an issue with the lab which has now been resolved, so you should find this works now.

I can confirm it works now. Thank you.

Also I'm not sure if this behavior is intended, but I was only notified about the vulnerability through the Target section. The output in the extender tab said there are 0 findings.

This extension should be run on the latest version of Burp Suite. Using an older version of Burp may cause impaired functionality.

Good to hear it's fixed. Yeah those stats are not very accurate, nothing to worry about.
