Lab not updating "Solved" status

Tanner | Last updated: Jun 28, 2024 02:36PM UTC

In the "Manipulating WebSocket messages to exploit vulnerabilities" lab, I have followed the given solution and the solution provided by the YouTube video, but the LAB status still says, "Not Solved". I am using Chrome with Foxy Proxy extension, and I also used Burp's built-in browser, and the lab still will not update. I am using the script "<img src=1 onerror='alert(1)'>" with Burp's Interceptor, it works fine, I get the alert in the browser, everything seems to be working just fine, but the Lab still says it's "Not Solved".

Hi Tanner, I have just run through this lab and been able to solve it using the solution provided so the lab does still appear to be functioning as expected. Are you able to provide us with some more detailed steps of how you are trying to solve the lab (some screenshots would be useful as well)?

Same thing is happening to me as well. Only difference though is that I did not look at the solution first. So I ended up sending multiple XSS payloads until one triggered. Before I sent the generic alert popup which is the intended solution, I sent a print() which does work. But the lab is not changing to "solved" status, even after injecting the proper "alert" to solve the lab.

Hi, As noted in my original message, it would be useful to see screenshot of exactly what payload you are delivering and how you are delivering this - I have just followed the written solution and solved the lab again so the more information that you can provide to us the better.

I think I switched from the Burp browser to Firefox, and it finally solved. Nothing else changed.

Hi Joshua, We have been experiencing some intermittent performance issues with the Web Academy environment recently - it is entirely possible this would have impacted the functionality of your attempts to solve this lab (it is having an impact on the timing of requests and the behaviour of the 'victim' when visiting the page etc). The team are looking into it but it is proving difficult to determine what the root cause is. Please bear with us.
