'DOM XSS in jQuery selector sink using a hashchange event' lab not solving

Chris | Last updated: Feb 09, 2022 05:58PM UTC

Hi I have successfully completed the lab entitled 'DOM XSS in jQuery selector sink using a hashchange event' however I am not receiving 'lab solved'. I have also followed the lab solution walk-through provided in case I missed any steps and it still will not give 'lab solved'. Any help you can provide would be greatly appreciated. Thank you CO

Hi, I have just run through this lab and was able to solve it successfully using the solution provided so it does appear to be working as expected. Are you able to provide us with the details of the malicious iframe that you are entering in your exploit server?

I'm facing same issue. I used following iframe and followed the given steps in solution section of this lab. <iframe src="https://exploit-ac321fca1f8d16e0c05f63a2011a005f.web-security-academy.net/#" onload="this.src+='<img src=x onerror=print()>'"></iframe>

Hi Avijit, It looks like you are using your exploit server URL, rather than your lab URL, in the exploit - you would need to use your lab URL in the payload in order for it to work correctly (as noted, in the written solution).

Hi Vivek, Again, you are using your Exploit Server URL rather than your lab URL in the iframe payload - as noted previously, the payload needs to use your lab URL in order for it to work successfully.

When I try to use the lab URL in the iframe payload, <iframe src="https://ac5f1f801f12aa99c9de600901c50049.web-security-academy.net/#" onload="this.src+='<img src=1 onerror=print()>'"></iframe> The Iframe loads with a 403 error Client Error Forbidden - Any idea what I am doing wrong?
