By the late twenty teens, our local networks have become populated by a growing number of devices.
If companies with such high profiles are failing to prevent against DNS rebinding attacks there must be countless other vendors that are as well.).
UPDATE (06/19/2018): Craig Young's simultaneous and independent research on this vulnerability was disclosed yesterday, just ahead of this post.
If you follow a malicious link on the web, the web page you arrive at shouldn’t be able to make an HTTP request to your bank website and leverage your logged in-session there to empty your account. (DNS) provides a useful mechanism of translating easy-to-remember domain names into the IP addresses that our computer’s actually use to talk to each other. DNS can be abused to trick web browsers into communicating with servers they don’t intend to.
Browsers restrict this behavior by limiting HTTP requests originating from a domain to access only other resources that are also located on that domain (or another domain that explicitly enables are different domains and therefor the browser treats them as separate origins. The catch is that modern browsers use URLs to evaluate same-origin policy restrictions, not IP addresses. DNS rebinding has received a few brief moments of attention over the past year when vulnerabilities were found in a few popular pieces of software.
Fast forward five years and it seems that Google has integrated that same mysterious API into all of its Google Home products, and as you can imagine, that undocumented API is fairly well documented by amateurs and hobbyists at this point.
In fact, earlier this year Rithvik Vibhu published detailed API docs to the public.Imagine a scenario where you’re browsing the web and all of a sudden your Google Home factory resets.
