  Orange is a legend and this chain is extremely impressive here.

  No memory corruptions, no heap shenanigans, just pure logic bugs, almost made easy to understand for the reader.

  As a bonus, they also posted a reverse chain: popping Edge from calc [0].

  I always felt bad about the whole site/browser cross integration that chrome and edge and others do. Now I feel really really really bad about it. Can almost see the marketing team's emails about what features to add, and the developers unwantingly writing the code not expecting such things to open so many holes

  • xnickb
    I think they very well understand that this code was full of bugs but no one cared. Likely was assigned to some junior who was making an entry into the team/repos as a non-critical task.

    And it's hard to judge them: I'd also rather focus on real features.

  It's very refreshing to read such clearly written and concise technical reports.

    No “here’s why it matters” and friends, thankfully.

  > with a simple fetch(...) with credentials included, you can easily grab any Microsoft Edge user’s email from any website

  Wow, this is disturbing on its own

• deburo
  I guess that explains the questions I had when I was mysteriously logged into Edge. I checked whether Chrome does something similar, and it can, but the setting "Sign in to Chrome when you sign in to other Google services" was set to "Don't sign in", so I'm not sure whether this is the default or not.

  > So even if you’ve never created a User Profile in the browser, just visiting www.microsoft.com is enough for Edge to create one and sign you in automatically.

  This is disgusting behaviour, RCE chain or not.

• Vaushite
  This is very awesome and cool.

  human craft is becoming rare these days

    Has been for a long time.

    It's more that LLMs increasingly outperform humans in finding vulnerabilities, so the share of human discoveries goes down.

    • account42
      That's downplaying how LLMs discourage humans from thinking themselves by providing an easier "good enough" path.

      • cubefox
        That downplaying the massive increase in LLM capabilities relative to the modest decrease in human capabilities.

  The popup nightmare never stops.

  This is amazing work.

  Excellent write up

  • russelg
    If you can understand nuance and context, you would realise the phrase right before that is saying that he's not going to go into details about how navigation itself works in Chrome/Edge, and to watch the presentation from Google itself about those specific details if you are so inclined.

    If you then continued on to read the remainder of the article, you would also discover that there was no AI assistance in this research at all.

  • est
    It's your loss. The whole article is very good written.

    • ncruces
      And much better for not going into needless detail.

      In fact, a problem with LLMs is that they consistently write more than I want to read.

  • maeln
    The article does actually go pretty in detail about the exploit.
  • MonkeyClub
    Same; either put in the work to think it through and show us your thought process and conclusions, or just post your prompts and call it a day and everyone gets to move on.

    • russelg
      If you continued to read the article, you would discover that he indeed goes through his entire thought process in building this chain. Including the fact this was done with no AI assistance at all.

      • MonkeyClub
        I stand corrected then, I’ll return to it!
    • tsujamin
      Imagine missing such a great bug-chain because an off-hand AI comment at the start put you off

      • cyclopeanutopia
        No need to imagine it.
