CVSS calls it critical at 10.0. It is confirmed in active exploitation. It sits in the 99.9th percentile for exploit probability.
🚨 Two stealthy vulnerabilities in Cisco IOS XE Software are being exploited with alarming ease! 😱 Think of this like a master key that not only unlocks a prestigious vault but also allows criminals to upgrade their access to the entire building. First, they create a new entry point, then they elevate their privileges to rule the place! An attacker can gain initial access and create a local user with normal permissions. But wait—then they can elevate those permissions to root level, allowing them to write malicious implants to the system! The potential fallout? Compromise of critical network infrastructure and devastating data breaches.
