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  • Widespread use of outdated protocols like IKEv1 increases attack surface for VPN products.
