In plain words

Think of a computer program like a house where you store your private things. Just like how you want your house to be secure, you want your computer programs to be secure too. The 'S' in Zoom is supposed to stand for security, but some security flaws were found in Zoom's macOS client.

What's broken

The two flaws are a privilege escalation vulnerability¹ and a method to access a user's webcam and microphone without them knowing. The privilege escalation vulnerability allows an attacker to gain more control over the computer, and the other flaw allows them to spy on the user.

How it actually works

The privilege escalation vulnerability works by exploiting a weakness in Zoom's code, allowing an attacker to elevate their privileges¹. This means they can do more things on the computer than they should be able to. The other flaw works by using Zoom's own features against it, allowing an attacker to turn on the webcam and microphone without the user's knowledge. This is possible because of a lack of proper security checks in Zoom's code.

Terms

¹ privilege escalation vulnerability: , A privilege escalation vulnerability is a type of security flaw that allows an attacker to gain more control over a computer or program than they should have.
² privileges: , Privileges refer to the level of access or control someone has over a computer or program.
