The article’s actual title is: Zoom Zero Day: 4+ Million Webcams & maybe an RCE? Just get them to visit your website!

But, assuming I’m reading it correctly, the “maybe an RCE?” part seems like fear-mongering, because it would require that Zoom lose control of one of the domains that they trust for transparent client installs/upgrades.

I’m also a little concerned about how some parts of the article don’t match up. For example, the “UPDATE: June 7th, 2019:” does not have (as far as I can see) a matching entry in the Timeline. There is an entry for July 7, noting a regression; but there is an update the next day (July 8) noting that the regression has been fixed.

Dangling domains happen all the time. As long as the main one that's actually used is still controlled by the org, others can quite easily slip through the cracks, not renewed while still present in the codebase.

  • Indeed! It's not even a hypothetical in this case. According to the article, Zoom was just 5 days away from letting one of the domains expire when the author told them.
