Cisco disclosed a maximum-severity zero-day vulnerability (CVE-2025-20281) in its Identity Services Engine that enables unauthenticated remote code execution and is already being actively exploited in the wild.
Summary
Organizations should treat it as an immediate emergency and apply patches without delay.
This is a brief wire summary — the full story (linked below) has the complete details.
KazaSec's take
Incidents like this rarely start with the headline event itself — they usually trace back to an exposed remote-access endpoint, an unpatched perimeter system, or a credential phished weeks earlier. The organizations that recover fastest are the ones that tested their defenses and their incident response plan before they needed them.
