CVE-2006-0764: The Authentication, Authorization, and Accounting (AAA) capability in versions 5.0(1) and 5.0(3) of the sof...

Security readout for executives and security teams

Cisco anomaly detection and mitigation systems with AAA enabled could let a remote attacker bypass login if TACACS+ was only partially configured. The issue is configuration-dependent and affects software versions 5.0(1) and 5.0(3) according to the CVE source bundle. Exposure is likely limited to legacy Cisco anomaly detection and mitigation deployments running versions 5.0(1) or 5.0(3) with AAA and incomplete TACACS+ configuration. Internet-facing or broadly reachable management interfaces would raise operational risk. Prioritize any confirmed legacy deployment because the issue can undermine administrative authentication. If these products are retired or isolated, urgency drops, but asset owners should still document non-exposure. Mitigation focus: Inventory Cisco anomaly detection and mitigation systems and record software versions.; Review Cisco advisory guidance for CSCsd21455 before changing production systems.; Check AAA/TACACS+ configuration for incomplete TACACS+ setup..
