Cisco VPN Concentrator FTP Banner Device Information Leakage Vulnerability

Cisco VPN 3000 series concentrators are a family of products for facilitating secure communications via VPN (Virtual Private Networks).

Under some circumstances, it may be possible for a remote user to gain access to sensitive information. The FTP banner reveals more information than necessary to negotiate a session. This could lead to intelligence gathering, and a directed attack against network resources.
