Why now
- Cisco's SD-WAN zero-day is currently exploited in the wild, requiring urgent mitigation.
- Fortinet and Check Point vulnerabilities have been recently observed under active attack.
- Security agencies have issued advisories and added these flaws to known exploited vulnerability databases.
Why it matters
- Active exploitation of zero-day vulnerabilities poses immediate risk to enterprise networks.
- Prompt patching is critical to prevent privilege escalation and unauthorized access.
- Widespread use of outdated protocols like IKEv1 increases attack surface for VPN products.
