stream failed to close correctly when uploading pictures

Cecilia | Last updated: Aug 04, 2023 06:36AM UTC

Hello, I have been using BurpSuite for a couple of weeks now, its been working fine, but yesterday I was doing labs and as soon as I have to upload any picture I get the stream failed to close correctly error. Even when launching new instances of labs it just doesnt work. Today, it says i have uploaded polyglot.php correctly on Remote code execution via polyglot web shell upload but on BurpSuite it states that a 500 error has ocurred and when I open the picture to get the solution nothing shows up.

Hi Cecilia, Does this still happen if you attempt these labs as of right now (your lab instances will have reset after this amount of time so it would be useful to know whether you still experience this behaviour)? If so, are you able to provide us with some screenshots of the Event log on the Dashboard tab of Burp and what you are seeing in the browser when this happens?

Hello, I have the same issue. I have tried this in several instances and always happens the same thing. Here are the screenshots from the event log and browser. https://drive.google.com/file/d/1DaqFQhx4eGcTXgVI7Lq718vjuTPE7VoL/view?usp=share_link https://drive.google.com/file/d/1PTR1Nul3tCXzb6FAKPbAZwQGf6y6GbQb/view?usp=share_link

Hi Can you please confirm the lab you were working on so we can check it here? If you refresh the page, do you still get the error?
