Arthur T Knackerbracket has found the following story:
Developer unknownv2 has released a proof of concept exploit for the Xbox One. The exploit leverages a series of known vulnerabilities in the Microsoft Edge Browser (CVE-2016-7200 and CVE-2016-7241). We have not confirmed if this exploit works here at wololo.net (yup, I still don't have an Xbox One...).
The Xbox One uses Microsoft's Edge browser. Pretty much the same browser that you used once on Windows 10, to download google Chrome.
In November last year, several critical vulnerabilities were found in the Edge browser, and disclosed by Microsoft as they patched them. A proof of concept was released for these vulnerabilities by developer Brian Pak, demonstrating how to use them in an exploit. This is known as the Chakra exploit, and a good read on the topic can be found here.
Hacker unknownv2 has built his Xbox One exploit on top of Brian Pak's proof of concept. In the developer's words:
The POC itself was mostly complete, but the first bug (CVE-2016-7200) it used was patched on the console. I used Json.Parse bug (CVE-2016-7241) to leak addresses instead and after a bit of tweaking with the values, I was able to get the correct address for the chakra.dll. From there, I modified the POC by changing the code addresses for the gadgets and the VirtualProtect function call to make the shellcode executable.
This is a userland exploit, similar to webkit exploits that many of us are familiar with.

Yes.
Because corporations should stay out of personal decisions on webbrowser. The only reason to not is to screw users.

Allowing end users to use a wider selection of applications, including third-party web browsers, increases a device manufacturer's support costs. Restricting usable software decreases said support costs, and hardware manufacturers pass at least a portion of the support cost savings on to end users. This contributes to the lower price of a game console compared to a gaming PC, and this lower price encourages end users to buy a game console instead of a gaming PC.
$299 for a game console or $499 for a PC: what would most pick?

I just want a general purpose computer that I control, thanks. Suckers who buy these game consoles are going to continue to be ruthlessly exploited by these scumbag companies.

It's not just about price, but about freedom. But the ignorant, unprincipled masses would probably pick the former.

Therein lies the problem. Without enough of the general public being willing to buy a mass-produced product, the economies of scale for efficiently mass-producing it evaporate.

I want a computing platform and no-one to impede my decisions on usage. It's not the manufacturers responsibility to handle users bad decisions, just to inform them of the supported one. And it's also my right to use whatever software I'll see fit.
Which just reminds me why iPhone is such a shitty choice for web-browsing. Whenever there's a problem with the rendering.. you'r STUCK.
