Скачать или смотреть When Zero-Touch Becomes Zero Security: The FreeBSD IPv6 UnAuth'd RCE Hack (CVE-2025-14558) Explained

FreeBSD is legendary for its stability, but a critical vulnerability (CVE-2025-14558) hiding in its IPv6 auto-configuration feature turned a simple convenience into a catastrophic backdoor. This video breaks down how a single network packet—crafted with just a few malicious characters—allowed attackers to completely hijack servers without passwords or privileges.

We’ll explore the mechanics of this 9.8/10 severity flaw, from the "misplaced trust" between system components to the simple command injection that made it possible. Learn how tools like Metasploit automated this attack, why OS command injection remains a top threat in 2025, and most importantly, how to patch and defend your systems against it.
