Security readout for executives and security teams

This issue can let a remote attacker crash a Cisco Prime Network Analysis Module monitoring process by sending crafted IPv6 traffic. The likely business impact is loss of network visibility from the affected NAM, not data theft or system takeover based on the provided sources. Exposure is limited to environments running Cisco Prime NAM versions before 6.2(1-b), especially where the appliance can receive IPv6 traffic from untrusted or broadly reachable networks. Treat as a monitoring resilience issue. Prioritize remediation where Cisco Prime NAM supports critical network visibility or receives traffic from broad network segments. Mitigation focus: Upgrade Cisco Prime NAM to 6.2(1-b) or later if applicable.; Check Cisco advisory guidance for supported fixed releases and deployment notes.; Restrict untrusted IPv6 traffic paths to affected NAM systems where operationally feasible..
