Orange is a legend and this chain is extremely impressive here.<p>No memory corruptions, no heap shenanigans, just pure logic bugs, almost made easy to understand for the reader.<p>As a bonus, they also posted a reverse chain: popping Edge from calc [0].<p>[0] <a href="https://www.youtube.com/watch?v=Bh1zglq4mLE" rel="nofollow">https://www.youtube.com/watch?v=Bh1zglq4mLE</a>
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
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.
It's very refreshing to read such clearly written and concise technical reports.
> 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.<p>This is disgusting behaviour, RCE chain or not.
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.
The popup nightmare never stops.
This is amazing work.
Excellent write up
Stopped at<p>> I won’t go into too much detail in this post, because I think in this era, you can just ask your agents to fill in the details :)
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.<p>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.
It's your loss. The whole article is very good written.
The article does actually go pretty in detail about the exploit.
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.
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.
Imagine missing such a great bug-chain because an off-hand AI comment at the start put you off
