What it is

🚨 A sneaky flaw in the CloudVision Portal could let any authenticated user become the puppet master of your EOS devices! 🔥 Think of it like a hotel where some guests have a master key that opens not just their own room, but also any room on the floor without authorization — a recipe for chaos! This vulnerability means that an attacker could manipulate, configure, or change settings on managed EOS devices, potentially disrupting services or causing data loss. The implications are severe, as it could lead to unauthorized access to sensitive network configurations and critical infrastructure management.
