CVE-2017-12319

Cisco IOS XE EVPN BGP vulnerability allows remote unauthenticated attackers to cause device reboots or corrupt routing tables, leading to network instability.

This DoS vulnerability in Cisco IOS XE EVPN BGP lets remote attackers force device reboots or corrupt routing tables, causing network instability. DIB orgs must ensure all network infrastructure is patched against actively exploited KEV vulnerabilities to prevent operational outages and maintain compliance with NIST 800-171 security requirements. Failure to patch known vulnerabilities exposes the organization to unavailability and potential data loss during critical operations.

Shame score — Cisco failed to patch a known BGP vulnerability that was actively exploited in the wild, causing network instability and demonstrating negligence in maintaining secure network infrastructure.
