arp-scan sends ARP (Address Resolution Protocol) queries to the specified targets, and displays any responses that are received. It allows any part of the outgoing ARP packets to be changed, allowing the behavior of targets to non-standard ARP packets to be examined. The IP address and hardware address of received packets are displayed, together with the vendor details. These details are obtained from the IEEE OUI and IAB listings, plus a few manual entries. It includes arp-fingerprint, which allows a system to be fingerprinted based on how it responds to non-standard ARP packets.

05d15c7172034935d1e46b01dacf1101a293ae0d06c0e14025a4507656f1a7b6NTA Monitor discovered a denial of service vulnerability in the Cisco VPN 3000 series concentrator products while performing a VPN security test for a customer in July 2005. The vulnerability affects Phase-1 of the IKE protocol. Both Main Mode and Aggressive Mode over both UDP and TCP transports are affected. The vulnerability allows an attacker to exhaust the IKE resources on a VPN concentrator by sending a high rate of IKE requests, which will prevent valid clients from connected or re-keying. The attack does not require a high bandwidth, so one attacker could potentially target many concentrators. This mechanism behind this vulnerability is similar to the well-known TCP SYN flood vulnerability.

3757ae9bdbba6788484a12d306d65e40e70d5721c7b1adb352c54fee941eaf06A vulnerability in Cisco VPN concentrators allows an attacker to enumerate valid groupnames on a through either a dictionary attack, or a brute-force attack. The issue exists because the concentrator responds to valid groupnames differently to the way in which it responds to invalid groupnames. The issue is believed to affect all models of Cisco VPN 3000 Concentrator: 3005, 3015, 3020, 3030, 3060 and 3080. It is believed that all software versions prior to 4.1.7.F are vulnerable.

The Vendor ID payload that is returned identifies the system as Checkpoint Firewall-1 and also determines the Firewall-1 version and service-pack or feature-pack revision number. This is an information leakage issue which can be used to fingerprint the Firewall-1 system.
