What it is

🔥 A sneaky loophole in Arista CloudVision's Zero Touch Provisioning can hand over admin privileges faster than a magician pulls a rabbit out of a hat! 🎩 Think of it like a hotel front desk giving out master keys without verifying who’s asking — suddenly, anyone can access every room without permission! 🏨 With admin privileges in hand, an attacker could not only query but also manipulate the system state of all devices under management. This could lead to unauthorized changes or even disruptions in service — a recipe for chaos! 🚨
