Cisco’s VPN 3000 Concentrator and much of its firewall line could be vulnerable to attack. The firewall vulnerability affects most of Cisco’s product line, including the PIX 500 Series, the ASA 5500 Series, and the Firewall Services Module embedded in the Catalyst 6500 switches and the 7600 Series routers. Cisco has promised to issue a software patch for the problem, but it is not available yet. The company did not give details on the problems reported by its customers, so there’s no way of sure whether they were hacked or simply locked out.”]
