Forced OAuth profile linking

Kelsey | Last updated: Mar 09, 2023 09:35PM UTC

The official solution includes instructions to create an iframe in the exploit server in which the src attribute points to the /oauth-linking... URL. However, the /oauth-linking response includes an X-Frame-Options: SAMEORIGIN header. How is this iframe expected to display?

I’m afraid we can’t provide dedicated mentoring for individual labs. Were you able to solve the lab using the provided solution or by following along with the community solution?

I completely understand, and perhaps I wasn't clear with my description. I am unable to solve the lab following either the provided solution or the community solution. While attempting to debug my issue, I came across the X-Frame-Options header issue I described in the original post, thinking this was preventing the simulated victim from opening the delivered exploit. I feel like this is a bug with this particular lab, so maybe this should be in the Bug Report category instead?

Thanks for the update. We've run through the lab here, and we were able to solve it by following the steps in the solution. You do need to be quite careful around steps 7-10 to make sure the code remains valid, though.

Hi Michelle. I have same problem like Kelsey. The code in /oauth-linking is alive, and we can do request to url https://lab//oauth-linking?code=value. But we can't use <iframe> as solution, because we have response with X-Frame-Options:sameorigin header.

The lab is solved, but we must use any javascript payload. I think, you must correct text text in Solution.

Hi Thanks for your message. Can you email support@portswigger.net with the steps you took to solve the lab and a screen recording of which parts of the solution caused you a problem so we can review the current steps?
