ARP-Scan ARP Generation Tool 1.9
Posted Jul 25, 2013
Authored by Roy Hills | Site nta-monitor.com

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.

Changes: This release adds support for ARM 64-bit CPUs and Dragonfly BSD, adds a --rtt (-D) option to display the packet round-trip time, uses libpcap functions to obtain the interface IP address and send the packet (to increase portability), requires libpcap 0.9.3 or later, raises the default timeout from 100ms to 500ms to avoid missed responses from slow-responding hosts, modifies the get-iab and get-oui scripts to the support new IEEE website URL and new file format (also fixes the -u option in these scripts), updates MAC/Vendor mapping files from the IEEE website, and adds additional arp-fingerprint patterns.

Changes: The IEEE OUI and IAB files were updated. Support was added for trailer ARP replies. Support for LLC/SNAP packets with the 802.1Q tag was added. Full help output is no longer displayed for usage errors. Apple Mac OS X Tiger, Leopard, and Snow Leopard are now supported. The license was changed from GPL v2 to v3. A DoS warning was added to the manpage and help output. New arp fingerprints were added. gcc compiler security options were enabled. "make check" tests were added. The Perl scripts were modified to work on systems where the perl executable is not in /usr/bin. Various minor bugfixes and improvements were made.

NTA 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.

A 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.

Checkpoint Firewall-1 version 4.1 and later with IPsec VPN enabled will return an IKE Vendor ID payload when it receives an IKE packet with a specific Vendor ID payload. 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.
