Cisco’s Comedy of Critical Bugs: Patch Now or Risk Unwanted “Root” Awakenings!
Cisco has issued a patch for a max-severity bug in its Secure Firewall Management Center software. This vulnerability could allow a remote attacker to inject shell commands, but only if RADIUS authentication is used. With a perfect 10.0 CVSS rating, it’s a hacker’s dream, so unless you’re planning to invite them over, get patching!

Hot Take:
Hold on to your firewalls, folks! Cisco’s FMC just got hitched with a critical bug that lets attackers play puppet master with your shell commands. It’s all fun and games until someone injects arbitrary code and makes your server their personal playground. So, let’s patch things up before they break up more than just your network!
